You do realise that "Uncivilized" appears to some to be an excuse for "Racism". Tarring an entire people because they aren't the same as you or follow the same laws you do doesn't exactly prove you are any more civilized than them.
In essence there has been no "uncivilized" people in millenniums en-mass. There might be a few hermits that lack social skills or prefer to be away from people, but even that doesn't necessarily make them uncivilized.
It probably would have made more sense to ask questions like:
Who are the most evil people?
Who are the most cruel people?
Who are the most corrupt people?
Who are the most rude people?
But state that "People" just means a collective of individuals that aren't necessarily directly affiliated with one another, let alone related.
Yeah alright, 'civilised' is a relative term. Different cultures never really understand eachother, but it doesn't mean that our way is better than their way. Science is only our Western society's version of the creation myth, right?
But is it really? In a civilised society we can expect infant mortality not to be through the roof, or most women not to die in childbirth. We can expect sewage systems that don't just involve shitting and drinking from the same untreated stream. We can expect people to have a basic knowledge of sexual and general health. We can expect proper education and basic levels of literacy in the general population
There was a time when the East was much more civilised than the West, and whilst the printing press was being invented in China the English were still being wiped out by the plague and waging war with virtually every surrounding nation.
However, there are groups of people on this earth who have always lived a primitive existence. It's all very well saying how a simpler way of life is just a part of their culture, but I wonder if you and the proponents of your argument could really endure the kind of life they lead there.
