My theater class of around 8 students is a safe space class where a lot of us talk about our issues when we have free time, for around a year now this girl, (B) has been regularly picking on me and my friends. Things like in appropriate comments, question, and flat out making fun of us. These questions are primarily targeted to me, and my best friend, (primarily about me being gay, and him trans) she's gone out of her way to pick on us several times, about 3 of us we're talking, our director even interjected telling us she had stolen and lied to her numinous times, so none of us really liked her. L is a girl in the class who is really chill with everyone, she a kind person who everyone likes. L said she's friends with B and asked us to stop talking about her, I told her if she didn't want to hear us talking about it then she should just ignore us. I know that the way L sees it we were "shit talking" her friend. But we were really mostly sharing stories about how annoying she is. She's sort of been bullying us and we were talking to each other in a safe space about it. L says that what I said was rude, personally I feel if she has a problem with us talking about her friends treating us like shit then she should tell her friends not to treat people like shit. My gf, who is also in that class will not talk to me over this. AITAH?
