Don't hold your breath as no such "explanation" is forthcoming. 'East of Eden' is clearly just another proudly ignorant, stridently uninformed, easily deluded parrot of the flagrantly dishonest & idiotic remarks of America's grossly incompetent, overtly racist, paranoid fascist & counterfeit President, spewing comically inaccurate, adolescent platitudes in response to anything that depicts their beloved tyrant Trump in any sort of unfavourable light, regardless of it's meticulously documented veracity (much the same way the object of their misdirected loyalty immediately shouts "FAKE NEWS" to the same factual accounts of his perpetually abhorrent & mystifyingly dishonest behaviour) 

Explanations require analysis and 'East of Eden', like the rest of the double-digit IQers that comprise the "Alt-Right" & white supremacist groups, possesses neither the intellectual capacity nor the supportive evidence to expound upon their unsubstantiated assertions & transparent grade-school rhetoric.
