Guy: They're [aka my boobs] attractive. I mean she's attractive.
Guy 4: *very politely and respectfully asks me about my views about feminism and men participating it*
Me: *has intelligent discussion with Guy 4 about feminism, describing the differences between first, second, and third wavers, and explaining that it's called that partially due to history*
Guy 3: I thought feminism was just about hating men.
Guy 4: *starts talking to someone else*
Me: No, that's just a stereotype. Some feminists may act that way, but that's not because they're feminists. Just like there are some atheists who hate religious people and act like jerks, but that doesn't mean all atheists act that way. Feminism is about equality between the sexes.
Guy 3: Then why call it feminism? That implies men are better.
Me: Well, like I said, part of it is historical. But men are still more privileged than women, so it's still called feminism.
Guy: But sexes already have equality.
Me: *head explodes due to the irony of this with his previous actions*
Now, I'm not saying all atheist guys are like this... Guy 4 was very nice to talk to. But I was the only female at this meeting, and if I didn't have an incredibly high tolerance for this type of stupidity or an incredibly high desire to be a part of an atheist group, I probably wouldn't come back. Not all guys are like this, but some of the good ones could have called out the jackasses.
