"Are you suggesting we embrace them whilst they stick a knife in your back?"

Not at all - so long as by 'them' you mean those who want to harm others or encourage others to carry out acts like we saw yesterday.

In replying to:-

"Isn't it high time that some effort was made to debunk all the nonsense spouted by these cult-driven extremists who are causeing mayhem throughout the World?"

I was asking the question as to who should be making the "effort" and how this effort should be manifested - there are plenty of groups ready to stir up hatred of whole sections of the population based on their beliefs, colour of skin, sexuality etc. without creating new ones. 

Those sorts of groups only provide the ammunition for extremists to carry out the kinds of acts we've just seen in London and NI - we don't need any more.
