One academic seems to think so. I must say, however, that once I moved over to the right side (in both meanings of the phrase), any guilt I felt seemed to melt away. Also, when I looked at the world from this new perspective, things made a whole lot more sense, and I became much happier.
My conclusion: genes, shmenes. Becoming--being--a conservative is better for your health than being a guilt-ridden, cognitive dissonance-impaired "progressive".
