fair point

currently, I just don’t reply

edit: My other thought was to really lean into agreeing with them. For example: The friend doesn’t explicitly embrace these people’s racism, but maybe it would make an impact if the friend witnessed me celebrating these people’s racism when the friend praises them for something else.

If you don't say anything, they assume you agree with them. It's a fine line between letting them know you (maybe respectfully) disagree, vs. actively debating, but in some cases I think it's worthwhile to try to let them know you aren't inside their bubble. Agree outright dickishness is unhelpful, but so much depends on the specifics of the relationship and circumstances of delivery.

I'm a blast. not really fair though, I don't associate myself with assholes so every party is a blast.

you poor sweet thing. you might be the brightest crayon in the box but that blunt tip makes it hard to stay in the lines. (I mean this in the most positive way. not all crayons are perfect, and they don't need to be)

I'll spoon feed it to you.

you responded to a post asking for backhanded compliments by outright calling OP an asshole for asking for backhanded compliments and had the audacity to not even provide what OP asked for.

I then took the opportunity to provide a tongue-in-cheek response that was a backhanded compliment and an appropriate response to someone who completely ignored the the whole point of the post.

what you did was akin to walking up to a conversation between people at a party, interjecting when you felt offended by the content that you involved yourself in, and called everyone an asshole.

what an asshole thing to do, right?
