All "truth" should be thoroughly examined before accepting it beyond doubt.
A lot of people misinterpret belief in the way that they confuse it with knowledge:
I believe in God vs. I know God
Replace 'God' in this sentence with whatever you like.
Now belief isn't dangerous, it helps people, gives hope, but you have to understand that with every belief there's doubt.
Now acting on your beliefs as if they were facts makes this so dangerous.
I'm curious to see what you think about this.
It might not be to clear what my point is, but i'm basically trying to point out the differences in dealing with your own thoughts. Everyone should question their own beliefs all the time i think, until we know it to be false or fact.
I believe knowledge is beyond doubt
