Hate speech in the US is not banned.
You can express the idea that one group of people are responsible for all the bad in the world, and that they are lower than an ant's navel crawling under the subway track of the Battery Tunnel, and you will have broken no laws. You only break a law when you tell people to physically attack someone.
In Europe, it is different. There, hate speech-running down a group of people without promoting violence against them-can get you arrested. But not in the USA.
Of course, it you do utter statements that blame a certain group of people, the government can't touch you but your boss can fire you, the neighbors can shun you, the paperboy can refuse to deliver to you, and you can't do anything about it. Speech is protected only from the government, how people legally treat you from then on is up to them.
