Elon Musk commenting more about what he means by free speech - and seems to be saying what
@mjcouvi was saying in that if it's consistent with First Amendment law, it should be allowed.
Apart from some basic misunderstandings about the will of the people and free speech (the government can't "pass laws" to make less speech), whether this is a workable standard for a website that you want people to want to go to remains to be seen. We already talked about hate speech and the Westboro Baptist stuff. So yes, profanity-laced tirades about Jews or homosexuals are in bounds.
Other examples of areas where the Supreme Court has said laws violated First Amendment rights:
- Crush videos (law against animal cruelty cannot apply to make illegal the possession of videos of women in heels crushing small animals to death), United States v. Stevens, 559 U.S. 460 (2010);
- Computer-generated child pornography, Ashcroft v. Free Speech Coalition, 535 U.S. 234 (2002);
