I would contend that, based upon the freedom of the will*, that you never were "born again". If you had truly been "born from above" the Holy Spirit would have conferred to you, via regeneration, a desire to "like it", and to continue to grow in grace and sanctification.
(* "Freedom of the will" - That freedom to do exactly what you want to do, and to do only what you want to do. (Note that this definition is required due to the fact that there are far too many people who believe that "free will" is the freedom to do that which you don't want to do.)
Now I don't know why that's what happened. I don't use it to judge anybody, anything or any God. I just know that it didn't sit well with me, not one bit, it became a rash on the back of my brain. Maybe I'll come back someday, but I seriously doubt it. I'm really happy being an atheist. It makes good sense to me and leaves me able to function without fear of what some supreme being might think.
