They know, but they never pester me over it nor do they bring up the topic of GFs and relationships when I'm around. They know there's no hope for me as surely as I do. They may not know of incels, but they do know I'm gonna be a virgin loser forever. They're actually pretty kind for not bringing it up/bothering me about it. I do remember being asked "do you like any girls at your school", or "you been chasing any girls yet champ". Ok, they didn't actually say "champ" but you get it. My normie brother has used my indefinite virginity against me in arguments before, which felt pretty bad. I do sometimes drop subtle blackpills when around what few friends I can manage to have (one of which is future incel for sure) they typically agree with most of it.
