My son keeps being racist to Mohammed?

I'm a Muslim, my wife is Muslim, and we've both raised our children as Muslims. So it's hard for me to understand and accept my 24 year old son's rejection of Mohammed, and his constant anti-semitic racial remarks he makes about my Saviour. I've been thinking about renouncing my religion so that he will stop tormenting us, and we can be a happy family again. I just need some help. I don't know what to do.
