Let's make sure this topic is worthy of debate then.
With regards to Islam, I simply adopt the libertarian American value system which gives everyone freedom to believe and say whatever they want, as long as they do not infringe upon the rights of others to do so. (The 1st Amendment right to freedom of religion, belief, speech, etc. is actually a side-benefit of the main purpose of the 1st Amendment, which is the freedom to criticize the government and educate one's fellow citizens about it. There is no 1st Amendment freedom in communist China, or probably in neo-soviet Russia).
Thus, for whatever religion, I honestly and sincerely do not care what a person thinks or does, as long as he or she doesn't impact other people's rights.
So, whether it is the Christian crusaders, or Islamic adherents, or Scientology fanatics, whoever infringes upon another person's right is in the wrong. Simple.
