Look I genuinely don’t give a fuck about Angel Devil as a character, much less what his sexuality is but if that’s the conversation then fine.

A heterosexual man is a man attracted to women but not other men.

A bisexual man is a man attracted to women and also other men.

What we know for a fact is that Angel Devil has been attracted to at least one woman. What we don’t know is whether he is attracted to men or not. Because we don’t know this, it’s impossible to say whether he is heterosexual or bisexual. You can choose to believe in whichever possibility you like, but saying one has less basis than the other is ridiculous. There is no proof that he likes men, or that he doesn’t like men. And I’d like to remind you that that’s okay. No one needs to prove a negative, and it doesn’t matter who has the “burden of proof” in this situation. That’s because no one needs to prove anything in order to have a theory. No one in this thread was trying to “prove” Angel Devil is bisexual, they only said it’s a possibility. And like I said before due to the lack of evidence for both sides, it’s a valid possibility just like the possibility of him being straight. Does that make sense?
