Have you heard about civil war? That was one group trying to convince another that some people should be allowed in.
And anyway; I wasn't making an abstraction but the very evil segregation such as rape victims meetups excluding men. Unsurprisingly these meetups don't exist in reality; there are some about violence or abusive relationships in general.
But is not the classic case of Ad-hominem, you did a deduction from point B to make a personal attack to deny the validness of point A. Interesting.
And say what you want, Im pretty sure white female rape-victims is not a valid meet up.

As you obviously know nothing of rape, and probably not much of women either, I really have to question why you're still typing. You seem to be woefully unqualified to be participating in any conversation about what _should_ be, even supposing, as you have, that such a conversation doesn't need to be informed with facts.
BTW, this discussion is just silly because there are millions of meet Ups in tech filled with only men, but in the other hand meet ups of rape survivors not accepting men would be just evil, men are a minority in that group, it would be like a tech company not accepting any women.
