Facebook is to “Free Market Capitalism” what a fish is to a bicycle.
They are a state sponsored monopoly—and should be trust-busted into a million pieces.

Along with Google and Twitter.

Facebook has as much right to ban the European Identitarian Movement from their site, as the European Identitarian Movement has the right to ban immigrants from their countries.
