The worst ones are like political science profs who spend years lecturing The Left about how Republicans are Fine and Good Actually and people should be Civil and Not Shrill and Engage In The Marketplace of Ideas then one day wake up and demand everyone is outraged as they suddenly are
the worst dudes online are the guys who are like “the time for electoral politics is over, it’s time for guillotines.” yeah bud i’m sure you’ll stop posting and get the ball rolling on the guillotines any minute now.
also related - people who demand you treat obvious bad faith liars (DC is filled with people who are PAID TO LIE IT IS THEIR JOB) as if they are operating in good faith.
like the ethos of "respectable" DC is completely lawyer brained which approves of making convincing arguments you don't believe. that's not necessarily lying, precisely, but it isn't good faith discussion either!
