P Z Myers wrote an essay for the Washington Post that reads as follows:
Atheism is the default position. You don’t have to do anything to be an atheist, but you have to work awfully hard to not be one…..
I consider this to be a falsehood, based on my own personal experience. I was raised in a conservative Protestant family, so I naturally adopted the basic Christian beliefs of my parents and other relatives. It required no work at all to simply believe in God and to accept the Bible as the Word of God. So for me, evangelical Protestantism WAS the default position; it was not until I was attending college that I decided to stop believing in God and it was at the end of a long internal struggle that involved some emotional wrangling that I never would have experienced had I simply chosen to ignore the contradictions I had discovered and remain a Christian. Thus I had to work very hard to deprogram myself and think freely from the dogmas of any religion. And I had to undergo this process TWICE, since I later was seduced to join the Baha’i Faith and then deprogram myself from that as well.
From a universal perspective, there cannot be a default position on religion, politics, or any other subject involving dogmas (and yes, atheism is properly classed as a dogma). There are only defaults with regards to family upbringings. The only way atheism can be a default position is if a child is raised in a family of atheists.
