".. because our founding fathers .." It's interesting to see that all sides of political dispute in US, even parties (like this one) which want to cater to the seemingly more rational and less emotional part of the populace use the argument of "the founding fathers wanted it this way, so... that must be the correct way of doing things forever".
The moment that the Founding Fathers cease to be the mythology glue holding the nation together will be the minute that the country fractures into 20 different nation-states.
No, it won't.
Because the Founding Fathers aren't now the mythology glue holding the nation together. American national identity is mich more (and much fuzzier) than that.
Appeal to the Founding Fathers is just a tired political cliche.
