Not weird at all. I would imagine they'd still have basic "human" rights they were born with, since that's what they were originally. They might also be afforded animal rights as well, (IE harming a human-side mutant would also constitute animal abuse in addition to any other crimes) but that's just a guess.

I don't think it would be considered bestiality, since they WERE human at one time, though some might have a more "racist" approach based on the fact they are no longer "pure" humans. There might be some morally grey areas in terms of how they are treated, but I think it would be on an individual basis, and probably tie in to how far they have become "animals" in looks or behavior.
