I think a lot of Bernie people honestly meant very well. I myself was a Bernie fan. I was definitely brainwashed into hating trump for a while until a about a year ago though. In the end, this is really about good vs evil. Evil exists wherever it can get power. Right left doesn't really matter although I can recognize now what socialism really means now. But going all the way to the right can be detrimental too. Not because the ideology is bad but because evil will penetrate people who only think in a one sided way.
Check out the book political ponerology. Super interesting.
