I'm happy to drive to why it is not, as you describe, nonsense if you are willing to have a critical and rational discussion.
Huh. So, what if we revisit this concept with the actual balance of ethnic power in the United States, as revealed by actual income and status statistics, rather than the WASP bogeyman that may have been true in 1963?
Is it no longer possible to be racist toward Brahmin Indian immigrants, second generation children of Chinese and Korean immigrants, Jewish people, and the broadly English/Nord stock that comprise the vast bulk of the Mormons?
This is great news, because I'm sitting on a pile of real zingers about Guamanians I couldn't use because it used to be racist. Now that it's not, the offensive jokes will flow!

Just for anyone reading this who isn't familiar: this is a radical theory and isn't at all a generally accepted idea.
And it's also a viewpoint that is more commonly held by the political left. I'll grant that too.
Describing it as 'radical' is something I'd disagree with.
Discrimination is making choices that negatively impact a group based on some criteria.
Racism is discrimination plus systemic power imbalances that enforce this discrimination.
