Thank you for sharing your reasons.

I was seeing more than militant atheism in this song. I thought that a more general message could be taken from it: use the strength of your reason, don't believe what other people tell you by faith, life isn't fair and we have to actively make it better. I'm still seeing all of this, to be honest, but at this point I have to admit the possibility that I'm biased, and my positive feelings about the music are conditioning me to see more in the text than what's really in it.
