One of the worst examples of muddle-headed thinking you can come across on the interwebs in the wake of the latest terrorist attrocities is the notion that somehow Islam is a religion of terrorism. Now don't get me wrong; I'm no friend of any religion, and Islam has some particularly loathsome aspects (it's treatment of women amongst them).
But to claim that Islam is all about terrorism is to ignore the mathematics of the situation; there are 1.5 billion muslims in the world yet only a miniscule minority are terrorists. If Islam really is a religion of terrorism, then there are an immense number of poor muslims out there.
The critcis of Islam will point out that the Qu'ran has phrases like :-
…slay the pagans wherever ye find them
And that is true, but it also has phrases like :-
whosoever killeth a human being for other than manslaughter or corruption in the earth, it shall be as if he had killed all mankind, and whoso saveth the life of one, it shall be as if he had saved the life of all mankind.
Most "holy" books are like this – you can pull out pretty much pull out a justification for anything you want. Any that applies to christians, hindus, sikhs, and just about anybody else. There are good and bad relgious people; bad religious people will support terrorism and good religious people will condemn it.
Yes there are some muslim terrorists and it would be helpful if moderate muslims would declare that the terrorists who commit acts in the name of Islam to be apostates. No other words are likely to have as large an effect as their co-religionists to formally kick them out of the mosque.
There are those who also claim that all terrorists are muslims which is just laughable; there have been many groups that have resorted to terrorism over the centuries. In fact if you analyse terrorist attacks in Europe up until the year 2010, the overwhelming majority were for causes other that Islam :-
