You are dead wrong on both points.

1. Conservatives are simply those who espouse conservative positions. Tankies espouse conservative positions. They are the literal definition of conservatives.

2. 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. (Although in the 30's, nazis often just referred to themselves as "conservatives".) In the U.S., an official "Nazi Party" preceded WWII. A different American Nazi Party exists today and members still refer to themselvss explicitly as nazis. Proudly. In fact, there are currently several organizations whose members call themselves nazis or neo-nazis.

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."
