You are dead wrong on both points.

(Trying a tautology like you did. Does it make the following more convincing? No? Must be a waste of typing then.)

Tankies espouse conservative positions.

They do not.

Nazis frequently call themselves nazis. In 1940’s Germany, you could be sent to a concentration camp for not identifying as a nazi. They used the word specifically.

Never head of that. My understanding is it was an anti-nazi slur, and they preferred the term "national socialist."

Conservatives are pathological liars. I do not respect my enemy, nor those who defend my enemy. So, without respect, “I don’t think you know what you’re talking about and should therefore butt out.”

I never defended them; use your brain sometimes - you might find it fun.
