No my above asserting is 100% ACCURATE, in fact it's entirely in line with CENTURIES (we've been around over 200 years you know) of well established Constituional law.
I said "decades" because it wasn't until, say, the 1930s-1940s that the Supreme Court started to take the concept of free speech seriously.
The idea that the Govt cannot censor speech based on its content is the entire purpose of the right to free speech.
There are *literally* hundreds of federal court cases that say just that with plaintiffs ranging from Jevohah's Witnesses to the NAACP to anti-abortion demonstrators.
Sorry you didn't get the memo.
