/Because it seems that a little more or less of half of people who say they are Jews don't ascribe to their particular position. Maybe it is time that they get their act together, a lot hangs on what they do believe.
Do you have any proof of that? Any poll of members of a major/large branch of Judaism in which even a clear majority says they are pro-life or opposed to homosexuality?
I'm not saying I agree with their position, but it's the rare day when over 50% of Jews agree on anything at all.
Just saying.
