I'm going to revoke the groomsman title and wedding invitation from my brother
Why do you not want your brother to attend your wedding?
His obnoxious behavior will ruin the wedding.
I can understand how you feel about your brother, but I think it is rude to uninvite ones brother from your wedding. I think you should talk to him about his actions and if he can't be civil then he shouldn't come. You don't want your special day ruined, but you also don't want to have regrets about him not attending.
I just don't want his foolishness around my wedding.
Then talk to him and tell him what behavior from him you expect. Don't uninvite him.
