Who is more likely to be a socialist: a Jew or an atheist? The General Social Survey asks people where they fall on a political scale from extremely conservative to extremely liberal. Maybe I'm stretching it, but extreme liberals could be characterized as socialist in a loose sense. Here are the percentages who are "socialist" by religion:
Percent socialist (N = 11,511)
All Americans 3.5
No question--atheists are easily in first place. I'm not surprised by the Hindu and Buddhist numbers. Just yesterday, I watched the Dalai Lama say on Zakaria's program that he is a socialist. The Dalai Lama! A socialist! (This shows why you shouldn't choose your leader when he's four years old--you can't tell if he's stupid). And look at how Muslims are on the bottom of the list.
These numbers suggest to a conservative that immigration from countries with high numbers of atheists, Hindus, Buddhists, and Jews should be discouraged. These tend to be wealthy groups, and the last thing we need are more influential socialists screwing up the country.
I looked to see if there are any immigrants who are disproportionately conservative. Protestants are the only group.
