Good on you for showing the underbelly of dating. The people who don’t mind racist jokes because it doesn’t involve them are about as useful as the Genovese rape murder witnesses. (https://en.m.wikipedia.org/wiki/Murder_of_Kitty_Genovese)
Racism involves all of us. Silence is acceptance, your permission to live in a place where people feel okay to not help other humans being hurt.
Thanks for not being silent.
