There is a first amendment to the constitution.
“Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.”
It’s clear as a bell; what need was there for a politician to make some law protecting free speech?
What’s happening is that we haven’t INSISTED on keeping it yet.
The First Amendment does not protect speech in private settings.
