The subs I've heard about banning were echo chambers dedicated to the idea that "this group of people I don't like ought to be [starved|exiled|thrown from helicopters|raped|enslaved]" and such things. If that makes you think the policy is "right leaning = bad, left leaning = good," that says some pretty nasty things about the modern right, doesn't it?
Ah, that's the crux: racism and misogyny are terrible enough that if you hate it, you must be correct. For me personally, the echo chamber on both sides is enough to keep me far away from both /r/politics and /r/The_Donald. For example, you cannot say anything positive about Trump on /r/politics. Nothing. There was a screenshot showing that there were 231 negative articles posted and zero positive articles. It's lite…
In what respects? As far as I can recall, the US did not just move from a monarchy to a democratic republic 15 years ago as a result of a revolution after loosing a world war.
I think the populist discontent behind Trump is real and concerning, but Pre-WWII Germany and current day US are very, very, different places. I think its fair to request that if you wish to make a parallel with Nazi Germany, you substantiate the claim with specific historic evidence.
