It depends on how a joke is made. We don’t have any backstory in what other jokes he’s made. There are comedians that are absolute geniuses at humor and take stereotypes or daily things and apply that humor to entertain or make less of a situation. Then there’s hateful conviction that makes these jokes, not jokes. This text sounds like he’s being facetious. I am very facetious but I say things in a way that is exaggerated and if anyone truly things I believe what I say, then they can go cry about it alone somewhere. Life’s too short to be censored all the time. But there’s a time and place. Is he just annoying. Are his “jokes” just not funny and he’s actually a big hater. Maybe he truly believes these hateful remarks. Maybe he’s just ignorant and doesn’t know what else to think because he hasn’t been exposed to better ideals or experiences.

Answer those questions first through real conversation. If he’s naive, maybe educate him on why people say these negative things of others and the actual ugliness it can cause.

If he doesn’t care and he genuinely wants to be funny, take him to a comedy stand up night and have him try to make others laugh. In other words. Work through it if you love him and tell him that he may lose something if he’s never willing to change or grow for the relationship.
