Some Atheists seem to be just as passionate about their Atheistic beliefs as others are about their Christian beliefs. They zealously defend their Atheistic beliefs, as others zealously defend their Christian beliefs. Christians cannot prove God's existence, and Atheists cannot dis-prove God's existence.
I think in many instances it's not being passionate about being an atheist, it's being tired of being told who/what/when/where by Christians.
As a Christian I confess I am tired of the same things from Christians who think I an not as Christian as they are.
