I may get yelled at. This evening I have become fed-up of 'Communities mourning young lad/family/whoever', especially the 17 yr. old from Dewsbury. They are practically rending garments in sorrow for him. Why, for God's sake? He's a murderer, repeat, murderer who took other lives in his idiotic suicide.
OK, rant over, sorry about that. The families and communities must bear a lot of the blame (as must we) in allowing these communities to establish themselves as 'different' in our society. Had all the incoming Muslims gone out to integrate fully in their host society, instead of separating off into cultural ghettos, their children and grandchildren would have been adherents of their birth society not some nebulous, misty, almost mythological 'Golden Age' in the Middle East.
Re. OP - methinks the families do protest too much!
