>The original Dick Grayson, Dick Grayson pre-New 52, & New 52/Rebirth Dick Grayson are all different people.
Technically the original Dick Grayson is a different person. He lived on Earth-Two, continued acting as Robin well into adulthood, even after Batman retired and died, and eventually he also died in the Crisis on Infinite Earths. However, Robin of Earth-One, the current Robin, has a history that is near identical to that of Robin of Earth-Two before the point where the two were established as separate characters, since the entire Earth-Two concept really only existed for characters who were rebooted after the '40s, like The Flash, or Green Lantern, and was, as a secondary measure, also used to explain away differences between the early versions of characters and the versions that would become the solidified versions, once the "early installment weirdness" was ironed out. However, Robin never really suffered from this early installment weirdness, or at least not much, so it barely effected him at all, and you can basically count all his pre-Earth-One appearances as canon to Earth-One as well. The biggest differences are probably just that Earth-One Robin was never in the Justice Society (I don't think he ever actually appeared in Golden Age Justice Society stories anyway, though he was mentioned), and I think Earth-One Alfred is considered to have known Bruce before Robin was around (since Bruce was a kid), while there is an actual comic, now considered Earth-Two, where Alfred gets hired, well after Robin is around.
Well actually technically, Earth-Two is not the real golden age universe, but an idealized version of it that doesn't mesh perfectly with the actual golden age comics, because the changes that differentiate Earth-Two from Earth-One appeared gradually, meaning that most golden age comics take place in a world that is mostly like Earth-Two but has Earth-One elements, and this earth is technically called Earth-Two-A. But this is never relevant to any actual story, and for all intents and purposes, Earth-Two is the Golden Age universe. But while I'm being this autistic, I might as well make sure I'm not technically incorrect.
But judging from how you only say
>The original Dick Grayson, Dick Grayson pre-New 52, & New 52/Rebirth Dick Grayson are all different people
when you said "the original," you probably just meant the version immediately before Flashpoint, and not the Earth-Two (or technically, Earth-Two-A) version, which only shows what a filthy casual you are. If you're gonna divide things along every time history was changed, then you should at least mention Earth-One, COIE-Zero Hour New Earth, Zero Hour-Infinite Crisis New Earth, Earth-0 (the last version of "pre-New 52" history) and then Post-Flashpoint. Rebirth is also a different thing that happened five years after Flashpoint, and technically didn't even change history, it was just revealing stuff didn't change as much as people thought, such as Wally West not actually being rebooted, but lost in the speedforce after Abra Kadabra erased everyone's memories of him. Superman: Reborn, which was separate from DC Rebirth but happened shortly after, did change history, but it's barely mentioned outside of Superman titles. Though it does provide much more time between the dawn of modern superheroes and "the present," so it technically changes the timeline to make it less cramped, but it doesn't really change any stories.
>They are not one linear fucking history you absolute baboon.
They are, though. Read the actual books. The same way you seem to understand that Zero Hour and Infinite Crisis didn't make Dick a different character than he was before those events, it's the same thing with the Crisis on Infinite Earths and Flashpoint (and especially Rebirth, since that didn't actually change history at all and was just a marketing thing).
Have you ever read the Crisis on Infinite Earths? The universes merge and the New Earth starts several issues before the end of the story. They make very clear that things are a continuation of before, but some things are different. Many stories in other series published around this time and in the next few years would also revolve around that fact. The exact same thing happens after Zero Hour, Infinite Crisis, and Flashpoint. Hell, Identity Crisis, one of the key stories that leads into Infinite Crisis, is all about flashing back to a JLA story from the '70s and looking at it from a different point of view, because anyone who actually reads the stories knows the old stuff is still canon. It seems from your complaints like maybe you read some stuff from between Infinite Crisis and Flashpoint, and you like that era best, but if you did read anything from that era, you should know that stuff from before Infinite Crisis is still canon, just sometimes with some differences, but even then, the original versions are still canon as well. (The JSA, for example, remember they were originally from Earth-Two but also remember the Post-Zero Hour New Earth versions of their histories.) You probably also noticed that Batman pretty much wasn't changed by that event. It just so happens he and all the Robins were barely changed by any of the Crisis events. Go read the books and you'll see.
>They just keep getting rebooted.
They don't, though, and Dick Grayson is one of the worst examples one could try to use to prove your point. Some characters have been rebooted, but he hasn't. Also, while I'm at it, I'll mention that sometimes the "reboots" aren't as simple as just history changing due to a Crisis event. For example, after the Crisis on Infinite Earths, Wonder Woman rebooted, but in that case it was a direct result of The Anti-Monitor shooting her with eye lasers or something and turning time backwards for her so she turned into clay again and then started over. So technically there's a story reason and technically the old stuff still happened. Also after Superboy-Prime punched reality, things changed so that that never happened and her Earth-One stuff was remembered again and just lead directly into her New Earth stuff. So they basically de-booted her. Another one is Hawkman, Katar Hol, infamously the most fucked up continuity in comics. This is because technically he wasn't rebooted. Technically, post-Crisis, they revealed that the Katar Hol we'd been following the entire time, since the early '60s, wasn't the real Katar Hol, but an impersonator spy, and the real one showed up and then we followed him from then on. Until they just killed him off eventually because shit just got too complicated. But it's not like he was just rebooted Post-Crisis. It's more complicated than that. Also after Zero Hour it got even more complicated as they tried to fix it but only made things worse, but I digress. Read the books and you'll see you're very misinformed about the actual events that take place.
Did you notice that things like Man of Steel and Justice League Origin take place in the past? Maybe you saw Justice League Origin and missed the fact that it takes place "Five Years Ago." The next arc takes place in the present, and the five years in between are there because that's the time when all (or almost all) the old stories happened, except for the ones that are directly contradicted. Same with Man of Steel. It tells stories over the span of ten years, or rather, it tells a series of stories interspersed between previous stories. The first one is ten years ago, and establishes that Superman first appeared ten years ago. Another one is a couple years later, and tells the new version of his first fight with Luthor, but we're supposed to think that the stories that took place between his first appearance and the first fight with Luthor still happened. Man of Steel is specifically about the things that changed, but it's written specifically so that (almost) everything else still happens in between its issues.
