There is a huge disparity of views being expressed on this thread but one thing that clearly unites everyone that's commented is the disgust that we feel toward this incident and the bastards who carried it out.
Circa's earlier contribution about the role of religion (not just now, but historically) is spot on. I for one am becoming less and less tolerant of religion - all religion, not just the currently, obviously extreme versions of it.
I don't know the answer, (not short term anyway) but it almost certainly doesn't lay in deportation. Even if that seems appealing, it won't necessarily make Britain safer - the world is too small these days.
Frankly, until profit driven self-interest ceases to be the primary motive of international foreign policy, UNEDUCATED, impoverished people who will look to justify the unjustifiable, i.e, terrorism will find converts and superstition (religion) to support their case.
Believe it or not, there are actually places in the world where religious bigotry and racism do not exist. I've got my own views as to how they've achieved that and I'll give you one clue - as I said on a previous thread recently when commenting how I missed the last match of the season - I've just returned from Cuba! But that's another story and another argument I guess.
The reality we face when confronted with the horror of what's happened to this young man, is so awful that (for me anyway), it leaves us off balance if you know what I mean. And that can leave us unable in the short term to respond rationally. That's probably why it's best not to have knee jerk reactions but I'm not going to criticise people on here who have said things about Muslims and deportation that I might usually disagree with. A lot of those comments seem to be coming from people who are otherwise generally open minded and would perhaps think of themselves as pretty moderate.
I'll finish on that note because if there is anything that characterises Englishness, (not necessarily more than other attributes) it's moderation. We're not Nazi's and we don't really want armed coppers everywhere do we? Let's hope the perpetrators of this atrocity feel the full force of the law!
