the only legitimate role of government is to ensure life, liberty and the persuit of happiness to those it governs, to achieve this all that needs to be done is stop people preventing others from doing the same. (the right of the individual to govern himself is absolute, anything otherwise is only when it concerns others).
any leader who ignores limitations of government enshrined in a constitution to anything other than the above is injust and illegitimate and must therefore be removed by the people. they being voted in by the people in the first place is irrelevant.
in regards to the inca, "join our empire or we will slaughter all of your people" and those ancient empires ruled by religion is hardly enlightenment philosophies or reason is it.
the whole idea of american declaration of independance was a rebuttal of monarchy and religious rule.
What about the flaws? USA 'leaders' continuously use the loop holes etc, are they in the right then?
Plus, in theory the USA has a religious element, but not in the belief of god, even tho its a very religious group of territories. It has been the land were serious racist and extreme cultist activity, most renown the KKK and white supremacy.
Truthfully, isn't that what you propose tho, everyones happy but if you're making people unhappy, you get punished, that it was the inca did.
We haven't progressed too much in political terms, we've just spent too much time giving everything a individual name and act like its brand new, we're just doing what the past did on a larger scale.
Also, what about the Roman Empire? They had religion, yet it was a fractured un-centred religion that was a belief in many gods, and lived generally happy lives, they removed what they saw as an uncivilised place as a required expansion to bring civilisation and 'happiness' to others.
Basically, what I am trying to say is, how does the happiness of the many, even if it is wrong cruel, murderous etc, trump that of the few who may believe in harmony.
What you're basically saying is if 3 people live in a country, if 2 people want the third raped and dead, and as its a majority, it must be for the good for the overall happiness. Also such things are entrenched like being happy is the ultimate goal of government, so therefore its fine to rape and kill the third one, no?
