My Step-Mom Just dropped the N-word casually in an argument.

Honestly just looking to vent. Let me preface this by saying everyone in this story is white, including myself.

I'm at my Dad and Step-moms house about to take them out for dinner. A conversation comes up about how my step-brother is being shitty, and I mention that I'm not surprised because he use to hang a confederate flag in his room when he was about 15.

My Step-mom says that he wasn't racist for doing that, and I pointed out that hanging the flag of people who defended slavery is a good indication of being racist. Especially since we live in the northern states and he has no "heritage" excuse to even fall back on.

I try and back out of the conversation, saying I don't want to get into it. Like an idiot, I don't leave the room and continue to respond as she defends him. Eventually culminating in her saying "it's not like he thinks all black people are [N-word]". I'm aghast, asking why the hell she would feel the need to just randomly actually say the word. She says she was just speaking as an example, I say that's still disgusting and leave.

Sounds like they still expect to be taken out for dinner but I don't want to deal with it at this point.
