I just saw this, going back through the thread to find that incredible moron his post first mentioning abortion, which maybe i wouldn't have to do if everyone who saw him mention abortion first would say so, and I'm pretty sure you saw it.
That aside, Snopes is addressing the rumor that Greenwood dodged the draft by running off to Canada. That is false. You could say technically he isn't a draft dodger, but he ain't no hero. And if he'd so glady stand up beside YOU whoever you is, (saps like bb mostly) and defend her still today (or do the lyrics also state "once again" I have to check), then one might think he'd done so before, and what is he waiting for?
