have you ever felt that your friends aren't so nice?

I'm not a person with many friends (actually, I just have 4 friends), and I love my friends, but sometimes I feel that they aren't nice to other people.

Look, once my friend 'G' showed me a photo while she laughed a lot. It was of a little Black girl posing with a monkey. I repeat, a BLACK GIRL WITH A MONKEY. I didn’t understand why she was laughing because, for me, it was just a normal photo, like, it's just a kid at a zoo????? After a few seconds, I realized that she was being racist... I was so like, what the hell? She’s white, but practically her whole mom’s side of the family is Black. I'M BLACK! How did she even feel okay doing that?!

another time, my friend 'B' started going on about a guy we know, and as we agreed with her, she started talking badly things about her appearance (including some fatphobic things). okay, he is boring and stupid sometimes, but talking about his appearance??? that's really low. G and another friend kept talking bad stuff about him with B, and i was just like "omg, my friends sucks, somebody help me TT"

I love them but, i dont wanna keep this friendship :(
