Politically I am kinda on the Left, and I hear the argument that the Nazis weren't fascist, they were far Left, or otherwise that fascism is a "Leftist" concept all of the time.
I am very worried that in reading this, someone might immediately think it is being asked by a holocaust denier, and then at the end, be worried that I am asking this as part of a political agenda or something. I've got no agenda, just trying to ask for objectivity in an area that seems to be affected by political movements currently.
This is asked and answered here fairly often. See this older post for a link to our FAQ and also some other discussion.
