I might be wrong, but quite often when people who know you (rather than just strangers, who are shit) are homophobic, it's because they have a possibly very low level frustration with it, but that it comes to the surface when they are frustrated by something else. Me and dad have flare-ups about politics and stupid stuff like that when we're stuck together for any length of time, and I know he's not against my politics or anything, but it just brings out the bad in them. So I dunno, don't misread it, but it's possible your family are pissed off with you for some other reason.
Oh God sorry man thats awful theyve taken it like that. Some people are really damn stupid. I mean REALLY. For Gods sake this is the 21st century...parents shouldnt assume their kids are going to grow up to be straight anyway! Hang in there man. And stay true to yourself As for whoever said "how can you knwo youre only 14?"...many, many people know at this age
Its good to hear your brother isn't beating you now. I hope I'm not reading into your parents 'not caring anymore' as they don't care about you, just that they don't care about your being gay. One day they all may wake up and realize what fools they are/were and will make amends. peace little brother, bob
