When I was a kid you could "threaten" to hit someone but as long as you didn't touch them everything was cool.
Today if you threaten even a bully (the government is the biggest bully of all), they will use force against you and claim justification.
Free speech no longer includes "threats" even "threats" made in defense of one's self.
If stand on your front lawn and tell a cop you will shoot anyone who comes into your house they will call for backup and come knock your door down and shoot you first and ask questions later.
This nation is literally in a state of perpetual war since 9/11, any use of force by government is immediately justified in their minds as a means to eliminate all threats, especially verbal threats.
