I think Chris Rock is making jokes about optional lifestyles, which is probably fair game. On the other hand, there are the cultural and socio-economic factors that can make such a lifestyle difficult to avoid, which, to a bleeding heart liberal, is less funny. Maybe Chris Rock does make racist or sexist jokes, but not in that excerpt, in my opinion.
You make a good point in The French Question (to his credit, so does HexHammer): that we set limits to free speech and it is the position of those limits that is subject to debate, rather than the principle. There is another point you make:
Wyman wrote:The concern is with protecting the public rather than with punishing the speaker for his intent....The same or similar reasons may support banning the speech in the Hedbo case.
I think a lot of the passion is from people who don't think we should be cowed by fundamentalist nutjobs; quite right too, but the point made by Lord Harries is that even though there are a lot of Muslims in the world, and a frightening number seem easily persuaded that insane brutality is the way to go, in western democracies, there is still a large number of decent Muslims who are vulnerable to abuse or violence stoked by what is perceived as anti-Islam sentiment by those too hard of thinking to get the joke. They are a minority of our society, regardless of what proportion they are of the Muslim community, do they deserve protection?
