AITA for calling out someone casually saying homophobic and racist slurs when they say it’s a joke

So, I usually spend my nights gaming with my old roommate online. At some point, my old roommate added me to his discord server with some discords friends he made a while ago, so new to everyone. It was going well until one of his friends ends up joining us for some matches on Marvel Rivals.

Instantly, I can tell that this person is the type that likes to banter and playfully make fun of others in a friendly way. However, when it came to me, it just seemed hostile and passive aggressive. Like when I was introduced to her, she replied to my hi with "who the hell has an username like….", or when she was talking to the group on voice chat and I’d try to chime in she would say "hey I wasn’t talking to you so shut the f up." At this point, I’m still trying to give her the benefit of the doubt and write it off as her banter like she does with the others.

But, it really crossed the line when she would call me homophobic and racist towards asian slurs to me during matches. Like "stop being gay for once and help me" or "what are you fucking doing, you ch*nk," are just some of them. And I called her out for them.

She then proceeds to ask me if I was both gay and asian, and I told her I was. She backs off there but then says that it was only a joke and that she has gay and trans friend who are fine with it. She also said that she has a close black friend on the server and she calls him the n word all the time and he doesn’t care.

But like, I’m a complete stranger to her and she’s already saying this stuff to me even though she has no idea if im comfortable with it and probably wouldn’t have asked if I didn’t call her out on it.

At this point, my friend and another person on vc tried to deflate the situation by laughing it off or changing the subject, but neither one wanted to get involved. She then proceeded to say that her night is ruined and that all she wanted was a nice night gaming with friends, but like her night was ruined?? She made such a fit that I can feel from the others that they want ME to apologize to her, or want ME to take the high road and forgive her.

At this point I felt like shit even though all I did was tell her I’m not okay with her calling me slurs.
