my real opinion is that there's kind of a middleground between these last two posts, but I'm going to ignore all of that and just focus on specifically the animal genitalia comment.
how is it a retcon? there's no evidence as to non animal genitalia existing beforehand. there's no textual proof that anyone in homestuck actually has genitalia at all. you can hate the dog penis without making up reasons why it sucks
i for one think it's pretty cool B) woohoo furries yay waow
the epilogues are the best part of homestuck
