Without freedom of speech, we would be mindless curs. We must have a strong dialectic tension to maintain TOLERANCE for free speech. You can't run a marathon by only running from your bedroom to your kitchen. You must stress the body to run 26.2 miles. The same is true for freedom of speech. You only know you have it when people tolerate listening to extreme views different from their own views. Freedom of speech is like flour to a tolerance tortilla.
If we limit freedom of speech, ultimately tyrrany will prevail. Any attempt to impose balance will only impose orthodoxy.
If you don't like what someone says, ignore them.
