Ardent, do you realize that you're arguing against the majority of the founding fathers about the need for a republic?
Do you really know better than them?
The fact of the matter is that a democracy will --->ALWAYS<---- become inhumane and then unstable. It's a certified fact for those who study history. The Ancient greeks were already teaching this fact!
The sad thing is that in the year 2000, the majority of americans still thought that a democracy is what they lived in despite everyone having to say the pledge of Allegiance to the flag at school. (Which clearly spells out that this is a republic.) Stupid peons...
The founding fathers are not inerrant gods and what was acceptable and even progressive in the 18th century isn't automatically so today. Don't forget the founding fathers also declared that black people were worth 3/5 of a white person, that slavery was perfectly acceptable, that women were not entitled to vote and a number of other precepts we don't accept today.
Also, most of the founding fathers were deists and rejected Christianity. While I actually think deism has a lot going for it I suspect their views don't reflect what most Americans think today.
