I'm a Discredited Author and I Approve This Message
I was about to call this a non-falsifiable argument until I realized that there was no actual argument. I guess it's a non-falsifiable irrelevance. (I've said that before, haven't I?)
Meanwhile, McCain himself was sent out to pose in front of working oil rigs, to testify to his thirst for pulling more black gold from the earth. The message couldn't be plainer: See that itty-bitty, little tire gauge? If you vote for Obama, that's how big your penis is. If you vote for McCain, on the other hand, your penis is as big as this rig, thrusting its gigantic shaft in and out of the ground! Real men think keeping your tires inflated is for weenies.
There may not be a sign tacked to a bulletin board at McCain headquarters reading, "It's the sexual insecurity, stupid," but McCain's team of operatives, many schooled at Karl Rove's knee, know just what to do when an opportunity presents itself. They've been playing this tune for so long, they don't need to look at the sheet music: Our guy is a real man, their guy is a sissy, rinse, repeat.
I won't more than mention the fact that Freud is no longer taken seriously in psychology.
For that matter, real conservatives are unimpressed with other attempts at exploiting “sexual insecurity.”
