@Arkos It really doesn't matter to these people; if there's a cute girl and the MC isn't fucking her, they feel personally attacked, so they make themselves feel better by calling him gay, a pussy, a beta, a self-cuck, or whatever the current trendy insult is for a guy who isn't a mindless walking dick that'll fuck anything with tits, regardless of the situation, the mood, or whether or not it'd be rape.
EDIT: And, as if to prove my point, in the time it took to type this comment, there've been several comments with exactly those insults tossed around.
