That is a reflection of what Norman Cousins preached to American educators, in traveling back & forth across America in the 1950s & 1960s, speaking to mass meetings of NEA affiliates, as well as college assembies. His recipe for accomplishing his goal of "surrender by subterfuge" (my term for it), was to shift education from teaching how peoples differed, to focusing on ways we were all alike. In short, but in functional substance, convincing the youth, that traditional America was not worth fighting for.
This, effective, "lets pretend" that we are all alike, was also a major contributor to the Teddy Kennedy sabotage of our immigration policy in 1965.

But for the Norman Cousins influence on American education, it is unlikely that Obama ever could have been elected. Certainly many of the spaced out looking youth at Obama rallies would have found a better use of their time.
