How? What I am saying is that people have the right to say what they want how is this different?
People have the right to
express any idea they want.Doesn't mean people have to like it, no, it just means they have the right to.
However, that doesn't mean you can go around spewing obscenities just because you can. That's public obscenity if you're in public or something, which, believe it or not, you can get in trouble for.
