Fascism and National Socialism were never a left wing ideology, as much as you would like to believe so in your conservative bubble world. Hitler despised Marxism and left-wing ideologies. And leftists despised Hitler. He promoted a hyper-patriotic 'nationalist' movement, based on an ideology of a white supremacy, which always has and always will be a 'right-wing' ideology. And Trump uses similar far-right themes and tactics (e.g. making a white supremacist his chief adviser, stoking hate and fear against a religious minority).

There is no giant 'progressive' conspiracy or rewriting of history, as much as you would like to believe, so you can deny inconvenient truths and facts that don't fit your perspective. You are literally creating your own reality, which makes a 'reasonable' conversation impossible. Try to broaden your mind instead of living in conservative conspiracy theories. Maybe listen or read some international news and see what the rest of the world agrees on as 'facts'.
