Are you suggesting that the Manchester arena bombing, where 22 died and 1000s of others were mentally traumatised, isn't rivers of blood?
Or the 52 murdered in London and thousands of others traumatised, not enough blood for you?
How about Reading, 3 stabbed to death by a terrorist, sunbathing in a park. London Bridge attacks, more deaths at the hands of a terrorist.
Lee Rigby had his head chopped off in a British street. Not enough blood for you yet?
The list goes on. Every civilisation in history has undergone conflict and strife when they've tried to become multicultural. once the minority groups grow, expect them to assert themselves, to the point of Balkanization of the British Isles. You're talking as if Multiculturalism is a done deal and it will only get better from here. Naive wishful thinking. The worst is yet to come.
