Oh, I leave open the door to the reality of "Bad Culture". Trust me on that. I see the danger of gangster racists from Mexico and Central America and West Africa (even nonMuslim ones). And I don't see any good reason to accept them in to the West.
But Religion has to be seen as multi-generational and far more difficult to eradicate than the family from Sierra Leone whose kids are thug leaning. That is my point. Islam is the central threat we face.
