I dunno. Sadly, many Jews don't even know what it is to be Jewish anymore. Their new G-d is Liberalism and it has its own set of commandments which don't match the old one. Many liberal Jews are intolerant of Israel because Israel must be militarily aggressive to survive--this does not fit into their world-view. Same with Orthoox Jews--they don't embrace homosexuality and still respect the old traditions. As a result, they are viewed on with suspicion and animosity by their liberal bretheren.
How did this happen? Very slowly. It has mostly to do with the tug of education (to the Left) at the same time that Rabbis lack the moral backbone to tell their congregations that they are wrong.
That being said, the above phenomenon is NOT just limited to the Jews. It infects the Christian Left as well. Which is why both groups are slowly disappearing. That is the fate of those who have ceased to believe in G-d.
Well said.
The old lure of the Golden Calf thing ... must be something about humans?
