I (33M) have a sister (30F) who has been a very big feminist for quite a few years now. Ever since a very toxic and abusive relationship of hers ended about eight years ago, she has hated men.

She is always making comments about how men are sexist, how there are no good men out there to date anymore, that none of them have the emotional maturity to date her, etc. She hasn’t had a boyfriend since the bad one, and refuses to look inwards and admit that her sh*t stinks.

It reached a new low this weekend when she was saying how she deleted her dating app because all men suck and no one wants to work on themselves. I told her to stop making sexist comments. She went off on me!

“Seriously? You need to look up what sexism is. You don’t even know what being sexist means. We live in a patriarchy! You act like you are just this great person because you have some leftist views, when really you aren’t. Just look at the guy friends you hang out with (she only knows 2 of them, 1 of which are a mutual friend of ours).”

She said some really hurtful things all in the span of a minute. Any time we drink together she gets argumentative, angry, and just unenjoyable to be around. It’s bad enough when she is sober.

I asked her where all of that is coming from, and told her that she needs to get therapy for her issues and anger, and walked out the door. Haven’t talked with her since. My mom was there and didn’t say sh*t about it either.

Is it acceptable to be done with my sister and to cut her out? She is a toxic and angry person, and clearly has some negative feelings towards me as a man.
