i have a friend with a habit of ignoring when people she is around are being horrible to others. she remains friends with people who say derogatory slurs about minorities, have abused people, have called her own friends (including me) bad things, and are overall bad people, and just makes excuses for them. she stays stuff like "i wont believe it until i see it" if anyone tells her about stuff they have said, and then brushes it off, and makes it pretty clear she doesn't believe us. she refuses to confront people and if she ever does she wont push them to change their behavior, and gives up quickly. i don't want to stop her from having friends, but i know these bad people aren't her only friends, and she just actively chooses to talk to them out of everyone she could hang out with. its starting to seriously bother me, but i don't know how to tell her i'm not comfortable being her friend if she keeps associating with these people. we've been friend for 6 years so the idea of cutting her off entirely really hurts, but her behavior is really getting to me.
