I have no idea if you meant "jail" literally or figuratively. If you meant it literally, our differences are irreconcilable. If you meant it figuratively, no, Dawkins had to face the consequences of retweeting the video. He got disinvited by NECSS, and he was subjected to a ton of abuse and harrassment on Twitter. He was threatened with violence, which is not acceptable by law. As far as I know, he did not press charges against anyone for that, so they go free.

What racist? There was no racism there. Why would you assume that all Islamists would be of a different race and/or nationality than Dawkins. In any case, Muslims are not all the same race either. He has written plenty against Chrisitians and some British political parties too.
> If that were the case ... publish it without consequence.
Well, that was not the case. Dawkins had to face the consequences of his actions. NECSS had to face the consequences of their own actions.
