Explaining Orthodox Judaism

I was trying to explain the various details about Yom Kippur to "B" who is not Jewish, and has met few Jews in her life. I tried going through the details about muktzah and fasting, and all the other stuff, and was dumbfounded at the weirdness of the whole thing. I then met "L" and mentioned that "real thinking is the biggest impediment to taking orthodoxy seriously" and he seemed to find that interesting.
