Dan, I will try to answer your difficult questions:
a) I eat Matzah on Passover. I also eat it many other times during the year. I especially like it with salmon cream cheese. Remember, I am a "cultural Jew".
b) As you know, I am a member of a reform Temple. I pray when I am there. I occasionally pray on my own as well. It is an emotional, irrational act. Please keep in mind that none of us are as logical as Spock on Star Trek (btw Leonard Nimoy was an OJ
).
c) I go to Temple and fast on Yom Kippur. YK is a very interesting holiday from a spiritual perspective. It is a day of deprivation. We learn a lot about our selves when we experience deprivation. Sometimes I cheat on Yom Kippur. When this happens, I do not beat myself up, because I do not believe I am breaking an ethical law. I am just breaking my spiritual experience.
I am a theist because I believe in G-d. I am a reform Jew. My conceptualization of G-d is very different from yours as an Orthodox Jew. I believe in a panentheistic G-d. S/he is non-anthropomorphic.
Now you might say I am not being consistent because if I followed pure logic, I would not do any of the things you say. Please keep in mind that we all do things that are not logical. But when do, there is a price we pay.
You pay a high price, on many levels, to be an OJ. Any btw, I do respect that !
