The Irony is that your whole story reads like a Jewish kid's "search for truth" cliche: "Both of my parents were radical leftists and quite antireligious..." How typical. So you wanted to rebel, fine, but join an organized religion? Why can't you just draw from all the traditions you've studied and come up with your own beliefs? How about starting a new religion called 'Think for Your Self'?

By the way, logically speaking you can't start with what you like about a religion and then come to the conclusion that its theology is 'True' ie that Mohammed was really a "Prophet" who flew up to "Heaven," etc. That's called cognitive dissonance dude and you shouldn't be bragging about it...
