Haha, I know where you were inspired to post this study, Ripclawe. I considered posting it as well, though I figured "Eh, this is going to rustle many jimmies here. Maybe someone like Ripclawe will do it first."
Anyway, I would state, as the study does, the comparison is more so between physical strength and "individualism," as opposed to a more broad "political conservatism." From the study, being physically stronger generally means you have the ability to rely much less on the government.
For many outside of gaming forums, this study is kind of stating the obvious. However, I understand this comparison really hits many guys on the left-side of the political spectrum to their cores, as it essentially implies "you believe in many of your ideals because you're weak." And that also explains why many are pretending to not understand the study's hypothesis, as understandably, really no guy, straight or gay, likes to be viewed as a "pussy."
Nevertheless, I'd say one's mental strength can easily compensate for lack of physical strength and then some, as far as being able to live a more independent life. Then again, envy of physical strength and individualism of others can limit one's potential mental strength as well.
