This is increasingly relevant.
"I can't remember where I heard this, but someone once said that defending a position by citing free speech is sort of the ultimate concession; you're saying that the most compelling thing you can say for your position is that it's not literally illegal to express."
This really feels like someone going full lawyer speak on why they can shut you down for having the wrong opinion.
Btw if this type of situation existed, but instead of freedom of speech based on speech, it was in regard to laws denying people a platform based on race (and civil rights didn't exist), then you can bet this stuff wouldn't be brought up at all.
Thanks for bringing up a great point, General Omega. That point being that the spirit of the law is to be obeyed, not the letter, and snarky technicalities such as yours will not be tolerated.
