as with most angry screeds, there's a bit of truth buried under the mountain of anger and over-simplification. But your evidence leaves a little to be desired ... I mean, I've seen professional bowlers before, and very few of them would be considered world-class athletes. Most of them aren't even "fit" by normal standards. And Barack O is, at the very least, one of the better basketball players in Congress, and I have no doubt he could out-run any of the Republicans you name (Bush Sr, W, and McCain).
As for the buried truth of your rant - yes, it is true that most women secretly find the rugged, un-PC masculinity (more often found in conservatives) more attractive than the timid, intellectual, "nice guys" (more often found in liberals). You see it a lot in DC - nerdy, "nice guy" types who pride themselves on being sensitive, wondering why they can't find a girl. But, of course, there are some nerdy, PC types who are Republicans and even a few rugged, masculine types who are Democrats.
The bigger issue is, what are you doing about it? If we're in such danger of "losing" to the (ahem) "Muslin Menace," are you going to stop it? Are you going to take any action, like a real man? You seem like you're resigned to your fate. That seems a little wimpy in its own right.
