John Stuart Mill did not believe that people should be shielded from criticism, even massed criticism, for fear that they might be victimized by their own bad feels. In fact: Mill believes that the preservation of free society and ordered democracy with equal access by citizens was one of the few reasons society has to limit freedom. As luck would have it, we're here today debating the very real candidacy of a person who proposes to strip Muslims of their citizenship rights, and of someone who stood on a debate stage and proclaimed that one of his first acts as President would be to ensure the imprisonment of his political rival.

Thankfully, nobody here is suggesting that the state should limit anyone's freedom (for that, you have to go to a Trump rally). Instead, we're simply criticizing Sam Altman for endorsing Peter Thiel.

There is no appeal you will be able to make to any liberal philosopher that people should be immunized from criticism.
