Vidiot, thanks for your answer to my question. I agree with your statement of '... the WTS is -by and large - an fundamentally conservative organization, and just because some JWs leave the WT, doesn't mean they leave conservatism per se. Not to mention that the conditioning to distrust "The World" can be somewhat difficult for some to grow past.'
I guess because I very rarely ever heard active JW's express their political views (as JWs are told by the WT to be neutral politically), because I live in a politically liberal geographic area, and because of my inclination to be progressive minded on social and environmental issues, and in some other ways, it did not occur to me (till I read your reply to my question) that a very high percentage of JWs are conservative on political matters (of those JWs that allow themselves to have political views). When became a baptized JW I begrudgingly accepted a number of the teachings of the Bible and the WT.
Kramer, you are right regarding the degree of education (if you mean the percentage who have college education) among JWs. After all, the WT has strongly discouraged (on many occasions) JWs from attending college and obtaining 4-year degree, and to read writings (and listen to ideas) that are critical of the WT's teachings and of the Bible. That influence of the WT even caused me to decide to avoid taking any courses (while I was in college) that would teach: evidence and reasoning in support of the theory of evolution and in support of the reliability of radiometric dating (including carbon dating), criticism of the Bible, and argements against the existence of God (any god).
I wish I hadn't let the WT's influence cause me to avoid courses that provide such information. I wish I had instead taken an introductory course in each of the following (or at least purchased a used college textbook on such while I was in college): physical anthropology, historical geology, biology, problems of philosophy (where arguments against the existence of God are considered), philosophy of religion (where arguments against the existence of God are considered and where teachings of non-WT doctrines of religion would be taught), and the Bible as literature (which might teach the Bible was not inspired by a god and which might say some of the biblical events never happened). However, during the years I attended college I did purchase a scientific book and science magazines which did have articles in support of evolution and I did read those articles and I did wonder, while reading them, if evolution is true.
Polls of religious people report that JWs in the USA have the lowest (or next to the lowest) percentage of members who have completed college and who consider evolution to be true, of all the other religions in the USA. In contrast, Jews and Hindus have the highest. The polls also say that of all the religions in the USA the JWs have the lowest (or next to the lowest) average income, whereas Jews and Hindus have the highest. In each of these categories the two groups ranked at the bottom are JWs and Baptists.
