There's this circle of friends that I go out with often, none of them identify as feminist but they don't really engage in sexist behavior either. Except recently one of them got into a new relationship and obviously she now too goes out with us.
She'd be pretty cool if it weren't for the fact that regularly when we're walking on the street, she calls other women whores and sluts for the way they look&dress. Similarily, she believes in negative stereotypes of women and views herself as the exception to the rule. My attempts to explain what the problem is have failed.
Do you have any experience with similar scenarios or ideas?
