How do I stop being a hypocrite?

I hate haters. I hate hate. I do. Whenever someone enters a discussion with hate speech, attacks on others, I then get upset and start acting the same way toward them! For example some people hate people of a certain race. I hate racists. Some people hate gays. I hate gay-bashers. So in essence I am hating on people for hating on people. I am a hater of haters. This is obviously hypocritical but I don’t know how to stop, because the behaviors of name calling and bullying upset me so much that I sometimes do it back… at the hater. This is causing extreme cognitive dissonance and I am now in distress. By being a hater of haters, I become a hater too. Thus I become what I hate! This isn’t a joke question.
