Fascists beat, kill, torture, etc. People who disagree with THEM . Antifa beats up fascists. THAT'S the difference. If you don't want to be beaten up by antifascists then stop showing up to fascist rallies.
I am a Christian, however, I don't take the bible literally and will never get why others do. Man is flawed and the bible was written, translated, and interpreted by man. Of course the bible would be too!
