Free speech protects your right to not be arrested or otherwise punished by GOVERNMENT institutions for things you say or actions classified as speech. But it does not protect speech that is intended and likely to cause violence or intended as threat or intimidation. As ruled in Manhattan Community Access Corp et al vs Halleck et al the Supreme Court's CONSERVATIVE majority ruled that: "The Free Speech Clause of the First Amendment prohibits only governmental, not private, abridgment of speech." On this basis, Google has a right to remove or report content to authorities as it chooses: Conservatives decided that free speech protections do not apply to private platforms. With regards to police enforcement: in Brandenburg v Ohio the Supreme Court held that the government cannot punish inflammatory speech unless that speech is "directed to inciting or producing imminent lawless action and is likely to incite or produce such action." Comments advocating for violence and murder ARE NOT PROTECTED FREE SPEECH, per this ruling. Similarly the ruling of Virginia v Black held that while some forms of hate speech may be protected on their own, that protection ends when the speech is intended to intimidate. To quote: "a state, consistent with the First Amendment, may ban cross burning carried out with the intent to intimidate." TL;DR: Free speech rights do not protect speech on privately owned platforms, and you can still be arrested for that speech alone if it incites violence or acts to intimidate others.
