Believe me, I have plenty of negative views about this country, and people in general everywhere, including the UK. I'm 61 years old had have seen a lot of lousy stuff done by humans everywhere, and have read a lot of history about times before even I was alive.
I just would prefer to keep such things away from what I hope is a friendly, accepting place for PHP developers from anywhere in the world: not a place where we single out certain groups for negativity. It's not a question of right/wrong, agree/disagree; but one of wrong place, wrong time. IMHO.
