Well, we KNOW that such is the case, the evidence has been posted and blasted all over the news but there is no way to take them to court. The courts do not care.
The problem is, as you point out this thread shows so well, is those attacks are not just coming from the left but the right is right along there with them. The Orwellian named 'Disinformation Governance Board' was exactly that and make no mistake, that has not gone away nor will it fail to get established at some point but listening to the right in every congressional hearing they had with Facebook and Twitter was just littered with politicians openly threating those companies if they did not do what they wanted. DeSantis even passed legislation along these lines even if being a state representative gives it no real teeth it was done. He is likely to take the presidency in the future though and that trend against private property certainly is not going to change any time soon. These are crystal clear violations of the first and the fourth without any hope of being reigned in.
At this point I am unsure if we are going to get past this with our fist amendment rights being recognizable anymore. What we do about it is beyond me though. You cannot fight something the VAST majority of people are demanding and, beyond that, none of them can be reasoned with. This thread makes that abundantly clear that facts are not even remotely relevant. None of these people understand fascism, how it is implemented or what role property owners play in a fascistic regime.
