It’s a leftover prejudice from the 1930s when republicans represented some sort of a country-club lifestyle which Jews weren’t welcome at. That’s the sort of prejudice which has a 25-year useful life i.e. the people responsible for whatever you don’t like about whatever it is will all be gone in that much time.
I think that’s probably why the Black community still sticks with the Dummiecrats. The country club stereotypes from yesteryear still ring strong in the community although the country clubs these days are very welcoming to the “right” kinds of blacks (Meaning that you’re more like a Bill Cosby or a Condi Rice type instead of a Snoop Dogg type).
The central reason for Jews being attracted to the Democrat party is the ideology of socialism/Marxism and the post segregation discrimination order that targets non-Jewish Whites. They enjoy the policy of suppression of cultural and social Christianity and have worked hard to cleanse the culture for humanism. At the same time, targeted whites moved to the Republican party and preferred Blacks moved to the Democrat Party.
Jewish Americans, spiritually, like the idea of “alms” through taxation rather than through the Christian-American idea of volunteer service to the poor. Service to the needy makes Christians more influential in society. The problem with this political alignment is that the only way genocide will occur in the US is with an unconstitutional centralized government where National education and police power can be harnessed to target and kill a large group of people. The Democrats are the party to carry it out. Aligning with brown, black and muslim racists and white radial self haters is the block of voters to do it. It would most likely target Jews and conservative Christians.
Liberal Jews hanging with conservative Christians in the Republican Party...the ADL will have to carry machine guns; they would surrounded by so many thought, social and political crimes and enemies. That is a lot of people to monitor, correct, condemn, and control up close and personal. The J-word would be heard without apology. It is a tad difficult to classify Christians as domestic terrorists when you are at a political rally with them. I am kidding, sort of. The realignment of Jewish Liberals into the Republican party would not be a happy marriage under the modern doctrines of political correctness. The good news is that conservative Christians would raise Cain if the Democrats went after Jewish Americans and Israel. They are loyal to the even the Jews who discriminate, harass and hate them.
Finally for the ADLish contingent at Free Republic, all of the above statements are to be seen “some Jewish people” and not “all Jewish people.” Jewish Americans like all groups are not all one thing.
