The disgust and anger is completely justified. It's fucking creepy for someone you trust as a friend to be looking at you with such dirty ulterior motives. It's just as creepy, disgusting, immoral as it would be for someone that you trusted as a teacher, a mentor or a guardian to look at you in such a manner. A friend is someone you become comfortable with and trust, you feel safe with them. A friend is like an auxiliary sibling. It's completely understandable that people would be uncomfortable and repulsed if they find out that their friendship has been soiled in such a way. An older adult might have been able to seperate himself, break off the relationship and move on without retaliating. But it makes sense that a teen so stressed would not be able to detach himself without retaliating. Bro is still able to care this much for that guy. He's a much bigger man than I would've been. I would've done my best to never cross paths with such a "friend" again.
Being gay doesn't mean that you have a free pass to disrespect other people. The same moral standards apply to gay people.
A lot of the audience here are women. Statistically speaking, you are likely to be one as well. Even if not, you must share a lot of affinity with the "feminine" culture, in order to have acquired this selective judgement that someone who identifies themselves with a vulnerable class can never wrong someone to comes from their corresponding privileged class. You know, the "I don't acknowledge or make excuses when a woman wrongs a man, a gay wrongs a straight, a black wrongs a white, a poor wrongs a rich" type.
So, here's a situation for you that you'd be able to more easily sympathize with. If this was, instead, heterosocial friendship between a straight man and a woman, where the woman completely trusted this guy to be her friend, saw him as a pseudo-sibling and let herself be as comfortable with him as she would be with her other friends only to find out that her so-called "friend" had never really been her friend at all and was always sexualizing her all this time. Would you not expect the woman to be thoroughly disgusted at such a "friend"? Wouldn't you understand if she chose to retaliate by shaming him within her close circle and community, in order to get back at him and also, to allow herself to gain the social affirmation and support that she would need to disassociate herself from the incident and move on?
so the ex friend’s thought process: oh no I knew my bsf liked me and he confessed to me so I panicked and called him disgusting and spread a rumour abt him that I knew would result in bullying
an actual dumbass
