More atheist than not.
I realized a few days ago that I have been atheist more time than the time that I was catholic. And I must note that I was catholic only because I was raised as one, and that for about 10 years I was an atheist who described himself as agnostic but only because I did not have the correct definition of atheist on my mind.
So, I have been an atheist more than I have not. That makes me happy. Cheers!
