I have blocked more in the last year than I have in the last 20 combined. There are far, far too many people arguing to troll, arguing in bad faith, threatening, or insulting that will do everything they can to bait you, derail your argument, DM you with insults, etc.
It’s probably because I’ve become far more critical of anti-science, shitty politics, and shitty people, so I’m sure that’s part of the reason, but nonetheless I don’t have the time or patience anymore to waste on the pigeons knocking pieces over and shitting on the chessboard declaring victory, so I block them.
I also have been blocked outright when presenting any objectively factual rebuttal. Facts are often strictly disallowed in the narrative, particularly political and anti-science ones. People don’t want their flow of internet “likes” interrupted.
The 2nd has been redirected in support of the new regime. Note that all other rights are under attack save that one, they need to keep the Right Rabble in line and ignoring the increasing temperature of the pot of water they’re sitting in by demonizing, blaming, and silencing critics.
