I've been reading this thread, and a theory occurs to me.
It is common knowledge that some 100 to 150 years ago, there was much more cleared land in the US and elsewhere, because much more land was needed to provide food. Now, if that's correct, and lets assume that it is, there would be much less land to grow trees, and thus less oxygen. At about the same time, liberalism and socialism were conceived and flourished for much of that time. It's my theory that the decrease in oxygen affected the thinking of the world population. Now, since our farming techniques have improved, more trees are growing, and socialism is in decline. Unfortunately, permanent damage occurred to the genes and progeny of a certain part of the population, now known as democrats.
Please don't send me a lot of information from educated fools trying to disprove my theory, which I believe is as important as the theory of natural selection.
