BS”D
Another very big issue, perhaps the biggest, is that I spent hmm..7 years, during 2 of which I was frum (from 8th grade in a non frum Jewish school through required courses in college), being taught that the Torah was written by man and that basically the Torah view of Hashem is not correct. The logical conclusion to draw from that is atheism; they actually taught that each shem Hashem was the name of a different getschke chas vesholom (and no matter what I don’t think that is correct and neither do non believing “Biblical” scholars today; I graduated college in 1988 when the Documentary Hypothesis was taken the way we take Torah meSinai).
It is very hard to forget that, especially when you don’t feel 100% comfortable in the community.
