[…] If you don’t support imprisoning people who hold these views that directly lead to the death of many innocent people, the taking over of people’s land/homes, the destruction of democratic systems, and the elimination of entire races of people from populations, then you are inherently tolerating their beliefs.

To me, it feels like you are conflating some things here: I draw a distinction between how I try to conduct myself (and, by extension, how I think society should conduct itself), and how I think a government should conduct itself. Any common overlap, while it may theoretically draw from the same core personal beliefs, is more of a coincidence in practice, imo. Yes, I think that society should not socially tolerate any of these behaviors, and I think that society should take an active position to socially oppose them; but I don’t believe that a government should take action unless the well-being of an individual is actively under threat.

I could be wrong in my interpretation, but all of your examples seem to simply a be a difference of opinion (no matter how abhorrent and unpalatable an opinion may be). I don’t believe that one should be legally punished for a difference of opinion. The only one that may have some legal ground, in my opinion, as I currently understand your examples, is

Supporting dictatorship, authoritarianism, or totalitarianism as a concept or goal

but that would depend on how you are defining “support”.
