Should hate speech be protected under first ammendment??

20. It's a fine line most judges and even the ACLU are reluctant to cross

There is a "Truth In Advertising" law on the books, but Fox "News" went to court to sue for the right to lie outright and still call themselves "News" and they won.

In Germany and Austria, neo-Nazi movements that don't get too flagrant are allowed a small amount of latitude, but gatherings with swastikas and Fascist salutes are prohibited, and anything resembling Nazi propaganda is forbidden by law (Fox "News" looked into a German-language arm, but it got nowhere).

Most democratically oriented countries are loathe to forbid any kind of speech, as that is usually the first step of a dictatorship. However, if a movement that is blatantly against free speech (and for violence) takes advantage of freedom of speech and uses it as a cover to gain enough power to inhibit free speech (e.g, present-day Turkey, and Putin is more than half-way there, too), was it a good idea to let them get that far? Who decides when such a movement has gone "far enough?" I know what's too far for me, but I'm not sure I'm qualified to say I always know what's too far for the whole country.
