Well, thankfully that is very far from the truth. Qv Alex Jones and other conspiracy theorists. Musk might let you say what you want up to a point, but if what you want to say is "Shoot all Muslims" even he might draw the line. The US has laws protecting free speech, but also laws curtailing the right to, for instance, incite racial hatred, or any other hatred, homophobic, mysogynistic, religious etc etc. I'm aware many US citizens view these laws as evidence of a nanny state etc etc. but if you've never been the target of such attacks, how the heck do you know what you're talking about? White male? Yeah, right!
