It's not. You can tell someone to discriminate. Once they do, however, it's a crime, and you could be a considered an accomplice.
What? That's just not right. If I told someone that they should descriminate against blacks, and they did it, it would be a crime?

What if I told someone to descriminate against skin heads? If they did that, would it be a crime? And would I also be considered an accomplice? Please... A double standard like that should NOT exist.

(I, personally would never descriminate against blacks, or tell someone to. However, I WOULD descriminate against skin heads, and I would tell people to do it also, without thinking twice. That should not be a crime.)
