This fits my experience too. Now it is time to take a brief look at why it matters whether atheism is a choice.
Suppose we decide that one's initial discarding of theism and one's continued lack of belief in gods are not conscious decisions and instead reflect one's appraisal of the available data. This has a number of important implications. For starters, it would make anti-atheist bigotry even less tenable. If atheism was not something one chose, bigotry directed at atheists would indeed resemble anti-gay bigotry or racism and would be as difficult to justify.
What else? Efforts at de-conversion might be wise to abandon persuasive elements and focus primarily on increasing religious believers' access to reality-based information. Then again, persuasion might still be needed to motivate religious believers to engage with the information. Still, I expect that de-conversion would probably change as a result of deciding that atheism was not a choice.
And of course, if we were to decide that atheism is not a choice, it would be difficult to avoid saying the same about theism. What implications might this have for how we interact with believers?
As an atheist, could you voluntarily choose to embrace theism?No, I couldn't. And based on the responses to my Twitter survey, most of you feel the same way. What would it take for me to start believing in gods at this point in my life? You can read my answer here.
