Well, my "tribe" is the people who see the dangers of global fascism under the false flag of UN "peace" and "progress", where the leadership is not subject to elective process nor the rule of law. Please join my tribe.
The US Constitution, as Sir Kicky has said, might have been written by men no smarter than himself, but they were the products of classical education, not Dewey Decimal socialist reductionism. They posited the values that human beings have innate rights because of their humanity that transcend any government claims of authority, and tried to set up a government subject to human agency but resistant to the hegemony of power-seeking cliques.
I agree with Jonah that we need a cultural shift towards more responsible morals, more concern for how our actions affect others, and a more just system of power that treats all people as equals if they adhere to basic human notions we can assert on some basis as "good".
I think most people who turn to Christian teachings after some sort of sinful life are trying to make a change for the better. some, not all, of course. I wish I could say the same about, say, secular humanists in general. Maybe, I've seen some like that, just not a general trend. Most, ime, when cut loose of belief in higher powers, go all Nietzche on us and start to believe they can do whatever they can get away with. That is, for example, how I see the Clintons..... maybe Trump, but I still think he's more of the old soft-headed back-slapper looking for a win-win deal with whoever he's talking to.
