Yes, and by way of example I'm thinking back to 2017. I had a mentoring relationship with a gay man who was a fairly newly minted adult. He had struggled a bit to come out, but he was doing well.

A friend of his kept publicly using the slur, "That's so gay," to refer to things he didn't like. My friend asked him to please not do that. He didn't make a big deal of it. He didn't cast aspersions. He just said the slur makes him feel bad, because he really is gay, and there's nothing actually wrong with that.

His friend not only didn't stop using the slur, he started using it more often, and he got very angry about his "right" to use it.

The two of them stop being friends of any sort.

It's hard for me to understand how somebody like your friend and my friend's friend could be that insensitive.

It's hard to wrap my mind around.
