Well, evidently it's already been altered then...
If someone says "the election results were legit" is allowed to stay, and "the election was rigged" catches a ban, then that ship has sailed.
To clarify, I'm not an election denier...I voted for Biden, Biden won. But if saying otherwise gets you removed from the town square, then clearly we've already crossed that line.
Ordinarily I would agree with you here.
That a person should be able to complain and say that the election was rigged.
And ordinarily others would then say, well show me your evidence and they would be able to see the evidence or lack of evidence in all its glory.
But, this situation wasn't ordinary.
You had many people saying it was rigged. Especially the incumbent president.
That's fine-ish albeit disgraceful when that president knew there was no evidence supporting this claim.
They went the legal route and were proven wrong 60 times in court. But it didn't stop there. They kept it up, they got the public riled up, and many were on the edge, wondering, perhaps hoping that a civil war would happen. On Jan 6 many of those people who were duped, who were riled up, crossed the line into violence, they attacked the capitol, attempted an insurrection, they were ready to kill politicians, they were waiting for Trump to command them.
So, at what point are private firms such as social media owners allowed to consider the "election was rigged" troupe to be more dangerous than merely an expression of free speech? When they think this is leading to violence and potential war, why cannot they decide that enough is enough and take measures such that their social media is not going to contribute to the riling up of people?
There is nothing nefarious about them shutting down this lie. They weren't doing it because they are aligned to Democrat party. They did it because they were worried about violence and war.
