On the other hand for those who leave Orthodoxy because of trauma, I doubt very much that they observe anything at all.
How we deal with all of this is beyond the scope of this post. But in the final analysis, except for “Orthoprax” Jews, I do think that there is a lot more to being Orthodox than just liking it. It isn’t that belief will automatically make you Orthodox, Of course it doesn’t. As Rabbi Fink points out there are a lot of ‘true believers who can’t even be in the presence of Orthodox Judaism’. But with rare exception – without its underlying beliefs I don’t think that ‘enjoying it’ is enough of an explanation of why people stay in Orthodoxy.
