As far as I can tell, I am the only person who has ever noted the correlation between the age of a religion and the tendency of its followers to be liberals.
Let's look at the four major U.S. religions practiced by people of European descent. Ordered by age with oldest first:
Now let's order these religions with the tendency of its followers to be liberal and vote for Democrats. Ordered by most heavily liberal first:
Notice that it's the exact same order.
Just a coincidence? I think not. There's a connection, and the connection is guilt. It's guilt which motivates liberals, and it's also no coincidence that Jews feel the most guilt. To make this post shorter, I recommend reading G. Andrew Duthie's post on liberal guilt. And then read Jewish Atheist's post on Jewish guilt.
Jewish Atheist's post is especially interesting because it explains how Jewish parents use guilt to ensure that their children marry within the religion and remain Jewish. I was raised Jewish myself, so I completely concur with the assessment that guilt is an integral part of the Jewish identity (though not part of the identity that I wish to be a part of). When I was little and I asked my father why we couldn't eat bread during Passover (or why we had to comply with any of the other seemingly infinite number of Jewish laws), his response was "GUILT! It's GUILT!"
If we hypothesize that predisposition towards feeling guilty is a genetically inherited trait, then it's clear why Jewish people are so wracked with guilt. Those Jews who didn't respond to parental guilt trips were more likely to abandon the religion and so the non-guilty genes were culled from the Jewish gene pool. And because Judaism is non-evangelical religion, there are no new members brought in from the outside. Jewish people are only born into the religion, and because those less prone to guilt compose a disproportionate share of those who leave, with each generation the average Jew becomes more predisposed towards feelings of guilt.
We have now solved the mystery that has befuddled political scientists. Normally there is a correlation between wealth and being conservative, so why are Jews overwhelmingly liberal despite being financially successful? Because of Jewish predisposition towards feeling guilty, which manifests as a liberal political orientaiton.
Jews aren't alone in using guilt to keep their children from changing faiths, which explains why Protestants are less predisposed to guilt than Catholics, and Mormons are less so than Protestants. New religions gain followers by converting the less guilt-prone followers of older religions.
Still don't believe that political views are related to genes? In my previous post, Politics and Genes, there's a link to an article in the New York Times about this very topic! Per the NY Times article, "a team of political scientists is arguing that people's gut-level reaction to issues like the death penalty, taxes and abortion is strongly influenced by genetic inheritance."
MAYBE THIS THEORY IS WRONG?
Maybe Jews aren't leftist after all? Jewish people are proud of our armed forces.
