When I came back to the US I found myself faced with a dilemma. For the first time in my life I was asking myself whether being Jewish mattered to me. I had long since stopped believing in "God" so what difference did it make? Why was I even asking myself the question?
I was asking myself the question because it did matter. Until then I always felt that people were people and it didn't matter. Being surrounded by non Jews for the first time I realized that there was a difference. It isn't something I can point to and say "that's it! That's the difference!" All I know is that it is there. And once again I think it's biological.
My ancestors went through every type of persecution and died in droves to keep our identity alive.
It definitely does matter.
I don't believe in "God" but I am Jewish through and through.
