Absolute nonsense. Nobody is obligated to be party to hate and bigotry. Those folks can have their own websites and try to promote it themselves independently of those who reject their trash philosophy. Platforming all thoughts and ideas isn't inherently valuable. Especially not after millennia of human thought and enlightenment.
Freedom of speech is meant to protect you from government squashing dissidence.
Out here in private land everyone is free to associate or not associate with anyone they please. This is what 15-23 year old libertarian brains have yet to comprehend. If you want to be a nazi, that’s fine, but there are consequences. One of those consequences is civilized society is going to quarantine you and isn’t obligated to take any of your shit. You aren’t entitled to any one else’s platform to spew hate.
