I was Wiccan for over 30 years...then shifted to just Buddhism practice and philosophy.
I am an Atheist Buddhist now....
So Wiccan before....and Buddhist now....doesn't fit neatly into your poll....
I went to sunday school ( church of Scotland) every sunday until the age of 15 and then to church until I left home at 16. I didn't realise at the time but the teachings went right over my head and had no impression on me so when in later life I took an interest in religion I could do so disspationately without any "baggage". I have met people who call themseves "recovering catholics" so I consider myself fortunate. Maybe there should be a group like alcoholics anonymous to help them ?.
There should be the option for more than one previous religion
