Thanks for Tuesday's post, Ellipsis. It was the third reply I've received to comments I've made, but the first to even hint that somebody had taken the bother to consider the point I was trying to make and respond coherently. However, you assumed I was talking about terrorism when I used the word "threat". I wasn't, I was talking about the cultural attitudes of some immigrant groups which are hostile to values which help to define what you would consider a civilised society. I gave examples in my first post.
As multi-culturism is not per se the topic of AG's post I'll stop banging on about it here and raise a post of my own on the subject. I invite you to contribute to it.
PS: I don't think Red Ken shares your views on vigilantism
