It's so pervasive that you can't even have an anti-censorship opinions on Reddit without getting lumped in with the alt-right and banned from subreddits. The nuance of "I disagree with you but defend your right to say it" is dying a painful death. Defend free speech and get accused of being alt-right or wanting to say the n-word.
Another thing dying is the defense of protests. I made a couple comments in popular Canadian subreddits about the truckers and was banned from a few for saying "protest isn't meant to make people feel happy and if the protestors don't make you feel uncomfortable you either agree with them or they're not doing their job". I got banned from one with the reason being "be gone nazi scum go try parler".
If you are talking about r/Ottawa, I can explain their reaction. What happened in downtown Ottawa was not a protest, but an occupation with heavy machinery in an attempt to make the PM look bad, and have to step down. There were many, many posters in that sub trying to paint the whole thing as a peaceful protest, but after a week of 150 air horns for ~18 hours a day, the benefit of the doubt was gone, and everyone repeating the same garbage was turfed.
Additionally, the sub saw many multiples of normal traffic, so mods were quick to ban anyone posting anything resembling a Fox talking point.
>What happened in downtown Ottawa was not a protest, but an occupation
Here's exactly my problem. This is the only narrative people are allowed to have on mainstream subreddits.
I'll admit it wasn't 100% peaceful but let's be honest here - it wasn't violent either and it wasn't an occupation. They demanded the PM step down or be removed by the GG because they don't understand how politics work here but visit some Canadian subreddits and what was done is widely regarded as a coup attempt. The view that it was a coup, or even an attempted coup, is literally insane and hysterical.
Regarding the length of the protest - Ottawa police sat on their hands and did nothing to stop or remove the truckers. When they finally did lift a finger to remove them they successfully removed them. It took 3 days but if they had just done something earlier it wouldn't have grown to as big as it did.
