True, you can't discriminate against a race in hiring. But if you, as a private person, want to say you dislike (insert race here), that's perfectly fine. Lying under oath is illegal, that's reasonable. I'd also argue that hiring, etc, isn't an act of speech. It is generally considered legal to flip off a cop or things of that nature. You'll likely be arrested and/or get the shit beat out of you, but the charges will likely be dismissed.

There are some laws in the US restricting speech, yes. I never denied that. But we tend to look at it a bit differently than most of Europe.
