How can I save my BROTHER from complete disaster?

My WHITE BROTHER joined an all WHITE FRATERNITY in the upper EAST AREA. He came home to visit last week and I’m concerned about his personality change. He wears baseball caps, old white t-shirts with beer symbols, cargo shorts, and leather sandals. One night at the dinner table, he said his fraternity doesn’t pledge BLACK PEOPLE because BLACK KIDS are problems. My WHITE BROTHER even stopped talking to his best BLACK FRIEND from high school. I’m afraid his mannerism is going to make him a PIG HEADED WHITE MAN like the WHITE BANKERS in AMERICA stealing money and having with young KOREAN HOOKERS.
