This is rally in London! The bearded man is holding a sign that reads:
Most demonstrations like this are organised by Salafi and Wahhabi groups, the most notorious of which is al Muhajiroun. They are consummate trouble makers, stirring public hatred for mainstream Muslims amongst the British population. Their leader, Anjem Choudary, is a follower of the Salafi cleric Omar Bakri Mohammed, who left the UK for Lebanon, but tried to come back to the UK to seek refuge in 2006 when Israel started bombing Lebanon.
They have a website advocating a distinctly Salafi ideology,in addition to some rather absurd designs on the UK, www.islam4uk.com, including a march at the end of this month calling for the implementation of Shariah in the UK.
Choudary, in his university days, was heavily into drinking and non-marital sex with non-Muslim women. Some Muslims think he is an agent of the British, implanted to stoke racial tensions to weaken people's resistance to various Orwellian measures that the government want legislated (eg, ID cards, long term detention without trial, etc). Personally, I don't think so, I've seen enough of these extremists to know that they are often hypocrites.
No question his sign is very disturbing but:
1) He might be a British citizen (even born in Britain).
2) I know he and his friends are not going to treat us the same way that we -in the west- treat them but as long as he only expresses his opinion (whatever that opinion might be), he can not and should not be arrested or put in the jail.
3) I actually think this type of demonstrations are counterproductive for them and good for the civil societies, as they show which type of people they truly are and how angry they've become and we show how tolerant and cool we are.
UPDATE: My friend who asked the question wanted me to be clear about the fact that he meant the question as a joke. "I know you did", I told him; "but I (naj) meant the question with the very visceral anger I felt when I saw this picture. This kind of extremism touches me very close at home." Yes, he (my friend) knows what tolerance is; and I wish he will never grow out of it by suffering the consequences of the intolerance the man in the photo is promoting.
