Taking away freedom of speech is a slippery slope.
We need freedom of speech.
Instead, what we should be doing is holding people accountable for their lies. This is not unprecedented in America, similar to saying you have a bomb at an airport or filing a false police report.
The question is, how do we do that when the cops, lawyers, "journalists", and judges are allies of the ones doing the lying?
"Who watches the Watchmen?", indeed.
There has to be a line for everything.
Advocating for the elimination of rights of some of our society should fall under that same category as "inciting a riot", and "filing a false police report". The Hippocratic Oath of "do no harm" should be in play.
For example, you can call yourself a Nazi freely and publicly, but you cannot call for the destruction of Jews, blacks, gays, etc. If you get caught doing it, you should be arrested for calling for the harm of other individuals.
The US thinks itself so great but it is and always has been setup to support the oppression and subjugation of any that the people that make up the government deem to be worthy of it.
So it can be the greatest country in the world, or a worse-than-the-Third-Reich fascist state.
Americans' actual freedom is in danger every four years, and every moment in between when the right-wing fascists are hard at work in Congress to win back an election they (cannot admit they) lost.
