As an Indian, I can assure you we have plenty of hat-wearing nitwits as well, and there's more in common in the ways Trump and Modi got elected than you think.
In case of unmoderated social media, just because law enforcement goes after them doesn't mean the content doesn't need to be taken down sometimes. Think non-consensual nudes, calls to extremism, etc. These things are filtered out because at some point even Parler and Ruqqus and all will delete them. But completely unmoderated social media will not allow for that.
I also never said that free speech was less important than dealing with the Parler crowd. I'm just saying it's a harder problem than it's made out to be.
