This guy is of course full on Paul bot, but understanding that bias, he still has interesting things to say. Definitely suffers from the pacifist bent. Yeah, it would be nice if every one was not aggressive, but certain nations always will be because barbarians sense weakness in a pacifistic nation, and are usually right in that analysis. . Of course I disagree completely about his comparison of abortion and paing for a war -- If that war ends up protecting you, your family, and your property from harm , then yes you should pay for it, and the Constitution IS (supposed to be) a binding contract - and that contract does in fact authorize the collection of taxes for war. The same logic doesn't apply to abortion. Unless you are going to argue (as freakonmics does) that a bunch of dead unwanted babies also means fewer criminals.. but I notice very few liberals make that argument in defense of public funding of abortion..
He point that you aren't party to the contract of the Constitution because you are born, and Jefferson's argument to that effect are all well and good, but as Madison exaplined- its just not practical. If we had constitutional conventions every 20 years the whole nations structure would be in question, and I can guarnatee you our decline into a socialist cesspot would have been that much faster- as we know only the worst people would have been attracted to those conventions--real people having better things to do and not having just fougt a war for their independence would feel less inclined to make sure those sacrifices counted.
Still worth listening to, if just for another perspective.
