Let me preface this by saying that I am not in favor of the war. Not at all.
That said, it strikes me as quite stupid that liberal protestors - or any anti-war protestors, for that matter - continue to use the "would you send YOUR son or daughter to Iraq?" tactic to point out the allegedly innate hypocrisy of government officials waging a war against a foreign country. All a politician has to do to fend off such an inane attack is say, "My son/daughter is an adult and capable of making their own decisions. Whether or not they choose to participate in the war effort is their own decision." That's it.
In fact, the most astute thing Dan Quayle probably ever said was similar to this. He was on TV stumping for anti-abortion laws and was asked what he would do if his daughter, then over 18 years of age, was confronted with an unwanted pregnancy. He said something to the effect that he would counsel her to have the child, but that she was an adult and it would ultimately be her decision.
Even when Michael Moore did this, it was kind of stupid. Parents don't sign their children up to go to war. What he should have addressed (and bless his soul - the man needs days of screen time to address the complexity of the situation, but people don't want complexity) was why the military finds most of its recruits primarily among the poor and underprivileged populations of America.
Then he should have asked various congresspeople to sign their children up to be poor.
