Or law enforcement. Or military. Or fast food workers. However, this person wasn't misusing any right, so again, that's pointless. There is no "within reason" clause to our freedoms, although I've heard that term used on numerous occasions. Demolition Man summed it up nicely, "I want to run through the streets naked with green Jell-o all over my body reading Playboy magazine. Why? Because I suddenly might feel the need to, okay, pal?"
Except remove the naked part, because that's illegal. Unless in protest, then it's freedom of speech.
I was only trying to point out the fallacy and inequality of the argument being used in the first place.
