That is in part because I see the path of religious addicts to emphasize some ritual or even something great like learning Torah just makes self righteous ass-holes. The religious world is a frightfully wicked horrifying place. Clearly there is some aspect of Torah they have gotten completely wrong.
My feeling is it is this very aspect of the combining Torah with Reason.
There is probably much more that that that is wrong but this at least seems to be an essential part.
