I had a friend who was very mildly homophobic, but used homophobic slurs and insults regularly just as insults. My best friend (and roommate at the time) is gay. I wasn’t going to let my best friend feel less than for no good reason. So, I told the friend he needed to cut it out or our friendship was done. He didn’t have a lot of friends. So, I knew it was impactful to lose me, but lose me he did because he wouldn’t stop.
