This really seems far fetched and disingenuous. I'm assuming that holocaust deniers are only 100% successfully deplatformed when the SPLC has absolutely free reign over which obscure groups and individual statements it may flag. In other words when the SPLC has literally 100% full control over the public discussion. How is this not totalitarian?

I've seen entire microcosms of people on twitter and facebook call for the murder of white people, I wonder if the SPLC would use some of their extremely extensive public funding to study that instead. (Hint: no)
