I don't see your correlation.
I think you need to deal with the fact that when it comes to rationality and reality, most Christian beliefs are comedic gold.
This is my life: wonderful son, wonderful boyfriend, wonderful up and coming career. I am happy with myself and my accomplishments, I enjoy getting up in the morning.
****Listen, we cannot speak for everyone. Atheism is not group-think, we have no pretend sacrifices, we do not congregate, doctrine, or otherwise.
However, from what I have seen on here, in documentaries, even in my own life, people who are using Christian beliefs as comedy are pretty confident and happy.
