Such censorship of free speech already exists in the US--just try to espouse Christian or conservative views in any ivy league school or major university.
Suppression of free speech is alive and well in Florida too! While visiting the great state of Florida with the Klamath/Sawgrass Rebellion, we had a couple of episodes. The one that really got my goat was the one where the cop tried to tell us that not more than 5 people could assemble was handed back to the LEO as what part of the 1st amendment contains only five people shall be able to peacefully assemble?
Scary when LEO's get PC for a religion and forget about the Constitution.
