If it's a fully private entity like Facebook, is it truly "censorship" in the derisive sense that we associate with it? If a user on Facebook posts aggressive and distasteful white identity propaganda which begins alienating other users, do Facebook and its advertisers not have the right to use the platform they created to exclude such content should they desire to do so? Does a fictitious "right to be heard" from a privately-administered entity supersede Facebook's actual right to property and self-determination over that property? If "censorship" is truly a problem here, only another free-market alternative to Facebook is the correct solution. Gab did it with Twitter. Now, whether or not Gab will ever be as successful as Twitter because of the userbase it curates is an entirely different story. One is not entitled to a specific outcome, and if rejecting racism is what makes big business big, there's not much left that the other side of this debate can complain about.
