It is indeed strange that the West that talks about reforms in Muslim countries fall over backwards to grant the same doctrines like Sharia to Muslims in their own countries.The problem with London is the problem with Chicago and Paris and Los Angeles and most of the rest of the free world. It's not enough to stick a nametag on a city and assume that its population can be swapped out with no social chaos or consequences.A culture is a consensus. Change the culture and you change the consensus. The Left-Liberals imagine that the consensus can be programmed by throwing enough TV ads, school courses and social media games at whatever bunch of people happen to be living in a geographical area. And they're invariably shocked to realize that it doesn't work that way.The human being is not a machine. He is a member of a group. And groups are naturally exclusive. Gangs are the group at its most primitive. Feral packs of young males on the prowl. And above the gang is the tribe, the community from which the group comes. Above the tribe is the nation.Multiculturalism leaves the nation part vague and strengthens the tribe. And the tribe naturally leads to the gang. The multicultural vision insists that populations can be defined by political identities regardless of their culture, race and ethnicity. And that is clearly not so. Nor can cultures be stripped of all their politically disapproved elements to create a harmonious multicultural paradise.The answer lies in stopping immigration of people who refuse to be part of the mainstream but insist on a carry over of the cuture back home they have left for ever.
