Prima facie, there is a number of observations that appear obvious.
Given that the part of the world inhabited by Whites - first Europe and then the West - is the only part to have embraced universalism, and one particular expression of it - Christianity -, and given that this is the part of the world that has made immensely greater progress in every aspect than the rest of the world, the first question to ask ourselves is whether and how the two phenomena - Christianity and progress - are in a causal relationship with each other.
This is of paramount importance, as there are signs that the West and the Whites are on their way to abandon Christianity, and some among them are even considering the next step - abandoning moral universalism in general -, which shouldn't be surprising, as Christianity is the supreme embodiment of moral universalism.
This seems to confirm the idea held by many philosophers and thinkers: that renouncing God is the first step on a slippery slope towards renouncing morality.
Abandoning moral universalism seems prima face to defeat the object. This seems to be the reasoning: we Whites are the only universalist humans; our countries are the best in the world; the particularists, ie all other races, want to take advantage of our generous universalism, invade our lands, displace us; therefore we should become particularist too, in order to defend ourselves and stop them doing that.
It may defeat the object if embracing particularism will make us similar to other races. So, in the end, the West would become like the Third World, one way - by invasion from it - or the other - by our becoming like it. Is a White Third World a desirable objective?
I say no.
Those who think that Whites, universalist and Christian or not, would never create conditions like those of the Third World should be able to explain in concrete terms what are, if not universalism and Christianity, the characteristics of Whites throughout history that produced a civilisation so superior to any other on the globe.
The barbarians that invaded Rome were Whites. What was so good about them that could have produced Europe's subsequent glory?
Who saved Europe in the Dark Ages caused by the Slavic and Germanic hordes that destroyed the Roman civilisation?
It was the Christian Church.
