good analogy muggaz. religion is a tool that can be wielded a number of ways. like any tool, it can do damage even when employed with the best of intents.
americans--for example--who decry the dangers of muslim theocracy while enthusiastically supporting a president who equivocates belief in 'creationism' with science and advocates forcing 300 million of his citizens to comply with the precepts of his narrow faith-based view of human culture are fools in whose hands a butter knife is dangerous to all nearby...including themselves.
But, the problem is that people have been and will continue to wage wars over the differences in religion, and when they do, it is because of the religious beliefs that they have which are different than anothers. This is nothing new at all. Just look at how long the Irish have waging wars amongst religions. The Christian God is viewed differently than the Muslim God, and so there is hatred back and forth. The same goes for Christians having problems with religions that don't believe in Jesus. Heck, there is even intolerance for different Christian religions. People are being blind if they can't see that historically religion has been the root of many hateful wars, and I doubt that it will stop any time soon.
PS- they are called Yarmulke or Kippah
