Tankies aren't nearly as harmful as Nazis, they don't make communities unsafe. You can disagree with a tankie and that's the end of it. With Nazis, it's completely different.
I don't know there's lots of people in these ML Utopias that would big to differ with you on that. As someone who tends more LM myself. Marxist Leninists are a very real threat and shouldn't be simply brushed off. You're not wrong and saying that they are not the same type or intensity of threat as Nazis. But given enough control and power many of them are ready and eager to assassinate/slaughter etc those they disagree with. It's more a difference of numbers. In the United States we've been indoctrinated and miseducated about socialism for over 100 years. To where people reflexively recoil at any mention of socialists good or bad. They don't really differentiate. To them all socialists are bad. Whereas over the last 100 years Nazism was modeled over groups here in the United States. Who've been in power and existed throughout all that time. If that ratio changed we would be much more concerned about the ML.
Yes I am aware of what it stands for. That is exactly why I use the term and call it out. While I may have a good bit in common with them being socialist myself. That does not mean that I approve of authoritarianism or government suppression. Something that comes with every authoritarian ideology whether they are capitalist or socialist. I can waste my concerns and try to be respectful about it. If they decide they don't want it No they're free to block it.
