I know several atheists and agnostics who look back fondly on their time as a believer. They believe that maybe ignorance is indeed bliss.
The late, great opponent of theism and belief in the supernatural as a whole, Christopher Hitchens argues that theism, the belief in a personal, caring, attentive, present God, is the wish to exist in a tyrannical system of slavery. If you can excuse his mild theatrics and strong rhetoric, he has a very interesting and I think valid point to make. There are legitimate and substantial reasons to shed your religious belief and good reasons to be happy about doing so.
Hitchens likens theism to a “celestial North Korea.” In most theistic religions, such as the Judeo-Christian-Muslim traditions, the devout believe in a supernatural being that created the universe, watches its inhabitants closely, and enforces his (because it’s a male) seemingly arbitrary law without exemption.
To believe in a being who exerts his all-powerful will over your life is to wish to be a slave, argues Hitchens.
I look forward to your thoughts in the comments. Cheers.

As a student of Religious Studies, I think it is fascinating to hear all sides of the theism debate. Thanks for sharing!
Thanks for reading. Hitchens has a slight flair for the theatrical but he makes good points. If you’re interested in reading more about atheism, I would recommend reading Richard Dawkins’ ‘The God Delusion’ and Robert Smith’s ‘Atheism: The Case Against God.’ Hitchens’ ‘God is Not Great’ is a good read but I found it to be less organized than these other two. Cheers.
