The danger of belief systems is when people act on their beliefs as compared to truths. I've been threatened by Theists on many occasions. I have yet to have been threatened by Atheists. There is that about brain washing that for all intent and purpose what ever some one believes it may as well be so. That is other than good logic and or even good beliefs. That's part of the difference between Atheism and or Theism. If/when Atheists pretend to counter Theists I think they should at least know what they are talking about before they knock some one else's perspective. And that is what I've seen on many occasions too. I also hold Science to the same standard. Take for instance the concept of solidity or particalness. When you get into Quantum Mechanics you find out solidity to be more about a system of change that repeats itself over and over so quickly for all intent and purpose it simulates solidity but bottom line nothing is solid. Theists call it spirit. Hmm.
