Seriously if Facebook can censor conservatives and it is not subject to the first Amendment, because it is not a public entity, but a private one, then we can all violate the first Amendment since we are all private entities. So can Walmart not hire a certain color people? They are a private company. Who thought this nonsense thru?
You cannot violate protected groups' civil liberties, such as race, origin, ethnicity, and so on in the public place. Look up Public Accommodation laws.
Freedom of speech applies only to government. Read the Constitution, please.
Private entities do not have to protect your freedom of speech.
