If you agree with policing hate speech, you have to accept the consequences.
Of course the 1st amendment currently only limits the actions of the US Govt. and corporations are free to ignore it. But this situation can't last.
In a world where every expression of speech utilizes a medium provided by a private corporation, free speech needs to be enforced at the corporate level.
Much like a corporation isn't free to discriminate against a person on the basis of race or religion for hiring purposes, it shouldn't be able to refuse to publish something because it finds the content objectionable.
