According to the scientific studies quoted by ces, it is the non-religious people (along with born-again religious people) whose brains are half the size (OK, I am exaggerating a little) compared to religious Protestants (who were not born again). I am guessing you don't agree with that?
Anyone who does agree with that is an idiot of a great magnitude, not least because it directly states that (roughly) ~85% of the worlds population are or will be mentally defective, with no scientific backing whatsoever (that seems to be the standard rhetoric coming from a religious person to me, we are better than you, you are worthless scum - I paraphrase, but the meaning is there).
Interestingly, the study was performed by associates of the Duke University Medical Center, one of the most highly regarded medical and research centers in the world.
Shame be upon them for having such a pathetic study associated with their good name (and it does seem to be a good name according to Wiki).
Unfortunately, the scientific study focused on religious beliefs and brain size, and not on political beliefs, so there is no science that I know of to support your claims.
Except that it didn't support any claims because the science was bad.
Did they cover other countries with different dominant "religious" belief systems, no they didn't, so by definition the sample size is too small. Very one-sided selections like this are worthless, it would be like testing 1,000 Scandinavians and boldly stating that "Sickle Cell Disease" does not exist - a worthless claim to make on a worthless study as there are people in the world outside Scandinavia
Likewise there are other countries that have a different mixture of religious beliefs which would dramatically change the outcomes so much that the current outcomes would instantly become as worthless as I believe they are, but they have not been studied, so this study is as worthless as my made-up example.
To give another terrible example of a rubbish bit of science (made up I hope).
More bad things (unlucky accidents) happen to people on Friday the 13th" regardless of whether they are superstitious, regardless of whether they have ever heard of "Friday the 13th" or even if they know its a Friday.
Anyone with an ounce of sense knows that this is utter shit that I have just written as an example of utter shit, someone somewhere will try to do a "scientific study" on this to "prove" that non-religious people (pick your denomination) are worse people because of some misunderstood passage written in a very old book of children's stories that has been heavily edited several times over the years and is commonly referred to as "The Bible" (which has incidentally diluted into over 1,000 separate denominations of "Christianity", and according to this study most of those Christians have or will have defective brains (another example of Religion being the enemy of modern man)), that would be another example of very bad science, or even pseudo-science.
If science is bad, the outcome is worthless.
If it is Pseudo-Science (Creationism as an example) then it is nothing more than a terrible joke with a rubbish punchline, the article that was originally posted borders on that lowly title of "pseudo-science".
