On more than one occasion, I have indicated measured support for our military entanglements throughout the world. Then comes the question, why don't you enlist?
The reason for the question is, I think, to undermine my argument by suggesting that I am either a coward, a hypocrit, or more charitably, an inconsistent thinker. One can't really support a military engagement without having enlisted in the military, right?
Now consider how flawed this "why haven't you enlisted" argument really is. Think of how many ideas or policies that you might support or oppose.
For example, I support vigorous efforts to clamp down on organized crime. I support the teaching of chemistry in high school. I oppose the sex trafficking in Thailand. I support drilling for oil in ANWAR.
Yet I am still waiting for someone to ask why I have not joined the police force, why I don't teach chemistry, why I am not rescuing teen prostitutes in Thailand or why I'm not digging holes in Alaska.
