Should you punch a Nazi?

Is it alright to punch a Nazi? Nazis are evil so why not? Everything about Nazis is evil, not only is it wrong to attacks somebody for their beliefs, it also weakens your stance. In attacking them, you've made them the victim, you've strengthened their cause, allowing for them to call their cause "just". Unless that Nazi punches you, you do not punch a Nazi.
I used to think that it was alright to punch a Nazi, up until I saw these lovely cunts. (Sorry if I offended, but I don't use it lightly if it makes you feel better :3 )
Antifa: Anti-Faschistische Aktion
This Organization is all about being against the Fascists and more specifically, the Nazis.
Doesn't sound too bad.
Except for that fact that they're a militant group full of anti-fascist fanatics that calls everyone who opposes them a "Nazi". They use violence and intimidation to get what they want.
cough cough Isis cough cough Terrorists cough cough
Because of their violent behavior.
Because of the absolute blind stupidity of their members.
Antifa does not have the moral high ground.
Antifa has shown how punching a Nazi is a double edge sword (At least for me)
They are why you should not punch a Nazi.
I'm gonna go finish making french fries. Have a good one.
