Told my boss off for having a copy of Hitlers RACIST book. Can I be fired?

I told him off about having the book in the company library about 10 mins ago. I think he was drunk and probably high on meth/crack/heroin etc. He laughed at me and said that it's just a book. I educated him about Nazis and post Holocaust trauma and he said his grandfather was a Nazi and asked id I have a problem with that. I used the F word and stormed out. Am I in danger of losing my job?
