I hear you, man, but we're going to come at this differently...for one thing, I'm Canadian, we're too damn polite for all that "a person should be able to say whatever they want wherever they want" business...
Kudos to you for having integrity, I guess... I just can't be bothered to get too excited about the likes of Alex Jones getting a couple private / corporate carpets pulled out from under him. If it were a case of being silenced entirely, I might think differently, depending on the content of his speech - we have hate speech laws up here, and I support them. But this isn't a restriction on freedom of speech, this is a company denying service for TOS violation. There are any number of ways he can continue to get his nonsense to market.
Also, please correct me if I'm wrong, as I very well could be, not being American....but doesn't your free speech rules include the prevention of compelled speech? And given that corporations are entities with rights, wouldn't forcing FB to allow Jones to continue to publish on their privately owned website constitute compelled speech? I tried to look this up, and it's a bit confusing, as A) some compelled speech is allowed while others is not (though Miami Herald v. Tornillo (1974) could be used in this case, maybe?), and B) I'm not sure if a corporation has all the rights as a person would... But, making all the assumptions required to make myself right (lol), it would appear that the true freedom of speech infringement here would be forcing FB to publish Jones.
Too far of a reach?
