I have a flatmate who is overall a good person but they would from time to time make racist comments like “ching chang chong” and do the slanted eyes with their fingers. No one says anything and finds this problematic. And when I call them out, they say that it’s just a joke. How do you deal with this??? I had the conversations with this person numerous times but they wouldnt even bother to listen …! It’s frustrating and when no one agrees with me it’s even more frustrating….
