Governmental choice really boils down to two basic points of view:
(1)Left: The Government's purpose is to "help people."
(2)Right: The Government's purpose is stay out of the way so that people can help themselves.
Jews are obligated by their faith to help people. If the government "helps people," it is therefore fulfilling The Jewish Social Obligation, (as amplified by Jesus!) and must therefore be righteous. If I support the sort of government that "helps people," I am therefore also righteous. If I am a non-religious Jew (or formerly from a Christian perspective), this also of course, has the added attraction of fulfilling a religious obligation for me ... by political proxy. For non-religious people of all backgrounds, The State is their righteous church, and/or the environment, and/or animal rights, and/or permaculture, and/or climate change ... vegetarianism, gun control, etc. ad nauseam.
The incredible smarmy self-righteousness of the Left, whether Jewish or not, is also very much a club. If I and my friends are righteous, perhaps you are not. I must be in charge of you, because, if you do not agree with me, you are obviously wrong and may do harm to yourself and the rest of us.
God says so. Or, God being absent here, The State.
After all, in Christian Europe it was the "Church" that ran the Social Welfare Establishment, not the state. In states run by Sharia Law, they would like to claim the same thing! If one disagreed with the Church Establishment, one could be in a heap'o'trouble. So now, if you disagree with the righteous religion of the State Establishment, you are also in a heap'o'trouble.
That's the way it's supposed to be.
Ever heard of the Salvation Army, or Catholic Charities?
