"I disapprove of what you say, but I will defend to the death your right to say it," has become a free speech cliché. But does that mean you must defend to the death the right of anyone to say anything from anywhere without any consequences?
In practice, people regulate the opinions they allow on their platforms, and pick and choose whose speech, and what speech, they are willing to defend. This isn’t a failure to abide by free speech principles. It’s a recognition of the basic truth that not all ideas are equally worthy of respect, support or amplification.
