Jewish people believe in ritual circumcision, they have a ceremony and the baby has his foreskin cut off, something that is very painful and mutilates the penis, and has no particular health value, according to many experts.
I am not trying to say that this is evil, or an indication that the Jews are barbaric, (I circumcised my own son, although I wouldn't make the same decision now) but trying to put this in perspective. We tend to excuse the ancient customs that we are comfortable and familiar with and demonize those of other groups, that seem strange and threatening. Both the bible and the Quran have things that are disturbing to most people today, because they were written in a different time.
I don't like the radical aspects of Islam, and I am an Atheist. But I see a huge difference between radical Islam and the majority of Muslims. Yes, there are disturbing things in the Quran, but that doesn't mean every Muslim believes in a literal interpretation of it, anymore than all Jews stone people, even though the bible approves of it. If you condemn an entire religion for the actions of a small percentage of them, then you are creating enmity of a very large group of people, when it is only some of them that are threatening you. This is not only stupid, but counterproductive. Attempting to ban Islam will cause all Muslims to side with the radicals and you will then have a much bigger problem to deal with.
It makes me sad to see the rampant racism and hatred that is flourishing now, because of these attacks of terrorism. There is far more at work here than the influence of Islam. Many of the adherents of radical Islam are not especially religious, the religion is just an excuse for their alienation and hatred of western society and their desire to be a martyr. I don't know what the solution is, but I know that racial and religious intolerance is not the solution.
