Atheists, tell me, a Roman Catholic: why should I become an atheist?

[chimp3]

@Balaco: It is of no concern to me whether you believe in god or not. I am not an evangelist for atheism. 

I can tell you that as a 13 year old catholic I rejected the church's teachings in a fit of youthful rebellion that has lasted until today- my 58th year of life. I remember my first atheist moment in 1972 taking John Lennon literally and going outside , looked up and imagined no heaven or hell below me. Felt good! Later on , my parents switched over to pentecostalism. I had little difficulty not following that family tradition.
