Hey guys, I've had numerous debates with various individuals I know who has recently taken up the far left ideology. One of the interesting aspects of their ideology I have noticed is the broadness of the spectrum with which they define fascists. I try not to argue definitions with far left people as the discussion always seems to break down into them informing of your apparent misconception of what communism is, or some weird idiosyncratic form of collectivism that attempts to patch up the obvious issues with anarcho-communism and communism in general. That being said, with so much talk of fascists I have been wondering exactly what is a fascist. I'm not terribly well versed in political ideologies as its more a hobby than anything, but it doesn't seem to me that fascism is as well defined as say libertarianism or communism. What is the far left meaning when they say "fascism". Also, is anyone familiar with their arguments for why Trump is a fascist?
