Diversity for the sake of diversity is just a fear of applying civilized
standards to other people. And it's not just the Constitution but
the Judeo-Christian framework that our culture and laws were
built around. No other culture has ever had the freedom we have.
What achievements do you think mark 'civilized' cultures?
Japan is a nation that rejects diversity. It is arguably one of the more 'civilized' nations in the world today, in terms of values that are worthwhile such as freedom and a strong work ethic and treating each other with dignity.
Japan could be argued to not really be founded in Judeo-Christian framework. However, after the Meiji restoration it did adopt Western methods in its restoration of Imperial Japanese rule. Of course, like so many non-Western countries, what had the strongest initial appeal to Japanese rulers was applying Western technology and rational social and busines organizational methods to autocratic and authoritarian models of government, much like fascism and communism leaders of the West adopted. It is a decidedly non-Christian framework, in terms of the model of individual freedom, and the humanity of the 'least of my brother' ideals that is at the heart of societies that consciously base themselves on Judeo-Christian principles. Nazi Germany and Imperial Japan based their societies on a raw and unmitigated will to power, and outside of Communism, there has never been societies that have been so barbaric to their core as those ones were.
Of course, with the defeat of fascism, Japan has in fact adopted the framework of not just the West and scientific method and technology, but now also of freedom, the freedom of a redeemed people even, as St Paul describes the world after the Cross. They have not adopted the belief system of Christians or Jews. They have however adopted the fruits.
And that is what makes Japan so civilized, not that it is Christian, because it is not, but it has adopted a framework that had made Christians of the West so free too.
It could be argued that countries like Nazi Germany and other autocratic governments were advanced, but they were never 'civilized', when civilized is used to denote something positive. The same could be said for many of the countries of the world today too. Mega cities and tremendous wealth generation and now the attempted restoration of Chinese traditions in mainline China makes that country increasingly advanced. It could possibly even surpass the technology of America in the near future, if Americans continue to base their educations on identities and quotas rather than on merit (see Heather Macdonald for reference). Yet can any country that is run by a fascist government be said to be 'civilized', in any positive sense of the word?
Certainly many of the advanced cultures and religions of the world have much to offer, and it is an attribute of Western modern curiosity that we tend to absorb what is best from other cultures like sponges. And as the world becomes more advanced and civilized, the obverse must be also true also. They sponge up American Judeo-Christian values and advance accordingly.
The adjective 'civilized' is always advancing too. The goalpost always keep getting moved further, and further down the field. What would be considered the acme of civilization in the Golden Era of Islamic civilization would be comparably barbaric today. The same is true with the marvelous civilizations of China of bygone centuries.
It has nothing to do with 'diversity'. It has everything to do with advancing the freedom and humanity and effectiveness of any society by adopting the best ideas that are available to all of us.
It shouldn't be hard for any of us to believe that Christianity has born the best fruits. Christians have had the best teacher possible in Jesus, aka God.
