Interesting question, and one I've thought about a lot at various times in my life. I'm now too old for it to matter, I'll never be drafted now, so I didn't vote in the poll. If they start drafting guys my age it means all is lost, and I might as well go off and get shot as try to do anything else, and take as many of the supposed bad guys off with me as I can.
But I have a 24-year old son who'd be prime draft material, so it's still a concern for me. If he were drafted, I would tell him the choice to go or dodge is his and his alone, and I would support whatever choice he made. I would of course try to counsel him based on my view of what he was being drafted for, but once he'd made his choice, he'd get nothing less than 100% support from his father.
That's part of what it means to be a father, in my not very humble opinion.
BUT... The question has never arisen, and as a citizen of Canada it is unlikely to ever arise for me, so it's too easy to take the high ground in the abstract. In reality, if my son were really faced with a choice like that, I would probably tell him to run, hide, don't put yourself in harm's way, for my sake if not for yours, dads aren't supposed to outlive their children, save yourself, I'll pay for passage to anyplace you want to go... He might be brave and honourable and feel a duty and etc., but I'd probably be a complete coward on his behalf.
You might notice I'm a little ambivalent here...
