I've stayed a christian even though I've dumped all the JW doctrines. For me christianity is a simple belief with no trying to shove it down other people's throats. I've enjoyed being able to look at things from all angles and understand the reasons why people choose not to believe in God or come to the conclusions they don't really know one way or the other.
The important thing for me is to enjoy what life is all about. My family, my friends, all my hobbies, travel, nature and all the other wonderful things there are. If it really does turn out that there's no God then what have I lost? Whereas if there is a God (and I truly belive there is) then anything after I die is a bonus
