I suspect there could be a frequency vs. intensity trade-off there. Fewer total radicalizations, but of the ones that remain, they may intensify on average. The "radicalization expected value" so to speak might go up even if the frequency goes down. (This obviously isn't to suggest banning is never a solution, but trade-offs do have to be considered.)
They're not questioning an election, they're making baseless accusations of fraud.
Conspiracy theories like Sharpiegate, hacked Dominion voting machines and Georgia election workers counting suitcases full of illegal ballots have been debunked. Trump's legal team has filed over 50 lawsuits to date, none of which have exposed any evidence of fraud or criminal conspiracy. The legitimate questioning is being done and the answer is, to an ever increasing degree of certainty, that Biden has won, and won legitimately.
QAnon nuts claiming the election is a coup de tat by Red China or a satanic cabal of Democratic pedophiles are not engaged in honest, good faith attempts at validating the integrity of the electoral process.
I'm not here to deny elections but I dont think much of it was including the machines going live on the net when Dominion said they didnt. They witnessed the packet traffic to international servers.
With regards to "debunking" on sites like Politifact you need to be careful. For instance they say the Smartmatic technology was not used in states that are being challenged when thats just not true. The tech is the same but runs under different banners and is all owned by Dominion. Also they focus on if Hugo Chavez family owns Smartmatic as the thing to debunk. Obviously thats not the case or the main convincing argument that is even being made. Its that the technology was used to game elections in Venezuela and that adopted tech is used in elections around the world now (why else would it be acquired unless they wanted the tech). There are no code audits because Dominion claims IP protection. Does that mean election rigging is happening? Not necessarily. But people have every right to ask that question and you should ask it too no matter what side you're on.
Partisan source? Maybe. But unfortunately the fact checkers have lost all credibility over the last few months by debunking things like, in the context of this article, hunter's laptop.
The federalist itself has spread a lot fake news over the years so you may want a better source to debunk the republicans in the state who literally ran the election who are saying it wasn't fraudulent.
Maybe you'll accept the credibility of the Republican lawmakers and election officials in Georgia who also consider those accusations of fraud to be baseless[0].
Nobody is talking about QAnon. This isn’t even about baseless accusations of fraud or claims that the election was stolen. This makes pointing out irregularities and sincere attempts to understand them bannable too. They already removed a video for this. This is a ban on even good faith questioning of anything to do with the election.
