It's spontanous for those raised in an atheist environment, as theism is spontanous for those raised in a theist one.
But I see where you're coming from in regards to linking it with those philosophies - if theism is wide-spread in a culture, one needs to first develop some critical thinking skills to come to an atheistic position.
And considering how much part of Christian morality goes against humanist values, it's no wonder that those who become humanists may also leave Christianity simoultaneously - but that doesn't mean that they therefore would arrive at an atheist position. Many of the early humanists instead became pantheists, deists, etc.
right this right here but I have to further think about your post...I'm so sleepy from a 12 hour shift but thanks for understanding what I'm trying to convey. I promise to be more thorough and clear.
