Yeah, right from a biological standpoint.
A homosexual couple can raise a child too though (but currently that correlates with worse life outcomes for the child on average due to a variety of factors and mechanisms) so a purely biological argument doesn't cover the whole concept.
But to play "devil's advocate" the demand to have homosexual marriage accepted same as heterosexual marriage arises from the fact that some people do live homosexually (no matter the reason) and thus it's good to have this formally recognized and aknowledged because legal, moral and social problems can be better addressed in such a framework.
They can still go fuck themselves about demanding a cake or marriage in a christian community though. Fuck that kind of shit, they can ask but not demand.
t.don't think I'm 100% straight
