I have two comebacks for that (one of which I thought of at the time and told my brother as we listened to it):
1) We're a nation with the freedom to be ignorant.
2) We're so far from our founding it's like saying a 49 year old thief and killer is a good person because he went to Sunday School when he was 9.
The guy admitted he hadn't cared about government politicks until after he joined the army. Idiot.
