Are you saying only Nazis are anti-Semites?

"They do not threaten me, and I am happy to let them live"
"If somebody is swinging a knife in your direction - you're not just FEELING under threat, you ARE under threat"
Surely you must concede the word 'threaten' can be used in a context which does not imply physical violence. I was, quite rightly I feel, confused by your statement which said nothing about a knife.

But that then raises the question of how the Nazi (your term) physically threatened you by shouting, "Jews will not replace us!". Remember you are prepared to kill this person without there being any physical threat to you or anyone else. He is shouting - not swinging a knife.

The laws of self-defence are complex if that is what you are going to rely on for going about shooting people. As a self-defense teacher I have the obligation to warn you, you will need a good lawyer for a knife/gun case.

You keep raising more and more questions. What is an 'ethnic group'?
