It's rubbish to say there is no free speech in France. I live here and there is a huge variety of opinions published every day, in the press and on TV. Not to mention a flourishing satire industry. What is illegal is 'incitement to hatred', the same as in many European countries. As for rioting, that is a classic case of 'free speech' and sensationalism in the US giving the wrong impression - most of it was related far more to economic and social issues than to anything connected to Islam. It so happens that many of the deprived and unemployed residents of the suburban areas where there was trouble are immigrants and Moslem - their status relates far more to their immigrant status than to their religion. It would be like me citing the fact that US jails have far more black inmates than white as 'proof' that black people are naturally criminal, when it is a complicated social issue rather than a racial one.
While I respect Bardot's record as an animal rights worker, she is an extremist who occasionally goes too far. The 'sheep-slaughtering' comment is an example. Unfortunately in today's climate some people will take her seriously.
