How do you deal with people who expose you in public?

People with low emotional intelligence are basically low emotional intelligence. He doesn't know how to communicate with others in public. He thinks exposing other people's shortcomings is a way to show his understanding of others. I think this is a very bad performance. If you change yourself into a party, you will definitely feel uncomfortable. If you change yourself into the exposed person, you will definitely feel sad, because everyone has a black history. I told him these things myself and thought about him, but he chose. I think even joking is a sign of disrespect for others. I will definitely keep my distance from him in the future. I don't think such people respect others.
