Excellent, I hope now you see my point. Of course people of all types become criminals, including plenty of nasty Englishmen.
If I've seemed to contradict myself, then I apologise, as that wasn't my intention. Usually I have only a few minutes between work tasks to dash off a quick reply, which can admittedly get one into trouble since it's only after a day when you go back and realise that you've buggered your post and contributed poorly to the discussion. I'm certainly guilty of that with regards to immigration and cultural matters, since as an immigrant myself with friends and family from all over the planet I'm guilty of treating the subject rather loosely. I'm working on that, as I don't want to needlessly offend. When my mates all get together we're a mix of Brit, Chinese, Italian, Caribbean, Ukranian, Guyanese, Polish and Indian (south asian), and our group chats on matter of race and culture can be both hillarious and heated - but we never take race or background all that seriously, but neither is it a forbidden subject.
On this post, I'll grant you that I could have been clearer, as the reader, not the writer is IMO the true judge of clarity. My error was putting in that comma before "especially in reference to any sort of closed or solo enthic gangs." It was gangs that I was trying to speak of, and how in my experience I can't recall any English-only gangs. That doesn't mean that there weren't any of course.
I'll also grant that you're 100% correct, in that all backgrounds generate criminals.
This is still a great discussion thread, IMO.
