Can civilization be transmitted

Jan Sobieski IV criticizes this view:

As Samuel Francis proclaimed at the first American Renaissance conference in 1994 in Atlanta:

…The civilization that we as whites created in Europe and America could not have developed apart from the genetic endowments of the creating people, nor is there any reason to believe that the civilization can be successfully transmitted to a different people. If the people or race that created and sustained the civilization of the West should die, then the civilization also will die.

So, it’s not enough to say whites built Western civilization in the sense that a long time ago whites started Western civilization — that the West originates with white people — even though many Alt-Righties imprecisely articulate their view as such. Rather, for the Alt-Right, whites perpetuate, maintain, and define Western civilization. They’re necessary, but more importantly, essential to it.

I am not sure that the Alt Right is making that argument.

But is the argument true?

It seems to me that Western Civilization could be transmitted to the Japanese, but then it wouldn't really be Western Civilization. It would become a Japanese civilization. How different would it be? That is hard to say.
