yes they can be. most of this is just who 'owns' the capital. Does the individual own it? Does the state own it? Does the state allow an individual to own it and they dictate what happens? When the argument should be about how monopiles (either state controlled or people controlled) are typically bad for everyone except the monopoly (and whoever owns it). One thing the socialists did very well was to hide the fact that fascism is a form of socialism like communism is too. If you read the nazi manifesto there are many aspects that are spot on socialist. Even the word 'nazi' is short for national socialist. The word is bandied around lot when people want to end an argument or make their opponent look bad. Without any thought what those people stood for.
I agree with your assesment 100%, People are just really simple minded and don't want to be grouped in or compared to nazis in any way share or form. Just look at all the emotional arguments presented in this thread alone by people who presumably identify presumably with more left leaning socialist values.
