Agree with RMAC.
Reading the discussion going on here and how intense, at times, it becomes is there any wonder that religious fanatics and zealots of any kind use violence as a means of expression.
We are a product of our environment/society. If you had been born in the 1920's in Germany its odd's on you would have been a Nazi or at least in the Nazi youth.
Its not excusable but there is a reason for the type of behaviour that occurs in the Middle East, just the same as what occurs in the deep South of America.
Its human nature. Belief is like hope and when it reaches the stage of fanaticism is a human disease that allows people to survive the most horrendous situation but at the same time commit the most inhuman acts possible.
I find it bereft of sanity to see arguments to limit weapons that mutilate and cause unbelievable injuries on the justification that this is not civilised and we are descending into inhumane behaviour. Get a grip, war is inhumane behaviour and its been going on since the caveman picked up a club ( you can imagine the committee on whether the club was an acceptable weapon "No its not allowed to be bigger than X and must be made of basalt wood).
What has the above line got to do with it all. We are at war with terrorism. Its not Marquess of Queensbury rules. We are human and always will be different, unless we end up like George Orwell's 1984, which is what Afghanistan was like (under the Taliban) and Russia was and China is and Cambodia was and Uganda was and North Korea is and kceflknhceflncefnj. There never will be a Utopia where everyone thinks and believes the same (thank heavens, what a boring place).
How does this explain the violent protest of the peace loving Muslims in living in Western cities. The same as it explains the Vietnam protests. The mob is easily led, particularly the young whom want to be part of something, anything and have a reason for getting out of bed.
What do we do. I think it would be acceptable to deport them to where this style of behaviour, violent protests and burning of flags and effigies is acceptable. Will that solve the problem. Nope but it would be nice to do something.
Are we getting to the stage were it has become obvious that we need to protect and look after our society and culture. Nope its too multi-cultural to do that.
