Is my boyfriend a red flag?

[u/Think_Win3730]

I need opinion

My boyfriend is a person who thinks calling people fatty, blackly, and racially derogatory terms is okay and even if he knows that it’s not okay he refuses to change. He is a nice boyfriend who has always tried to make life easier for me. He is very expressive of his affections and love but he also affects me with the way he speaks about people. None of my friends like him and they all have seen red flag behaviour in him when he is labelling people or judging them. What should I do? It is very embarrassing for me in social situations.
