Everyone. Basically. Eventually. Collude. Not a lot of facts in use.
So your answer, to privately owned Facebook restricting speech, is to use the power of the US government to force Facebook to carry your speech? So you think conservatives are better off in a world were the government decides what speech is carried and who carrys it? All so you can be on Facebook. Net neutrality was big for Freepers whining about not getting or paying extra for Netflix. Now its whining about being on Facebook.
Everyone is not on Facebook and it is no more a Town Square then the shopping malls of old. This ploy is nothing more than a dust off of the Fairness Doctrine.
Yes and no. Yes it should be up to US law on how forums are conducted. Such as braking of any laws. The real question is what does it mean to "disrupt a public forum"
Because these social media's are political forums. Politicians do use them to communicate with citizens. The US supreme court has already ruled on that.
They should be under freedom of speech laws.
I don't think there is a real clear answer to what "disrupt" means. Which is left to the forum operator to decide. That is the real issue. Facebook gets around this by claiming it's not a forum at all and can delete anyone they feel like.
Facebook is supposed to be a platform, rather than a publisher. But recently, they are leaning towards to being a publisher. In that case, it changes the game completely.
