Atheists, would you be willing to die for the cause of ridding the world of religion or belief in gods?

No. While I disagree with religion, I also believe in freedom of thought and expression. I would not sacrifice my own life in order to force my own views onto someone else. The religious have the same rights as I do, and as long as they don't force their ways on me, I really have no problem with them. However, if a religious group tried to take away my own freedom of thought and expression, I would willingly stand against it.
