The cultural differences were more pronounced back then so politically, it was easier to emphasize racial differences. American imperialism had not yet penetrated the psychology of non-white races. Now the cultural differences aren’t as pronounced, so it is more difficult to emphasize racial differences without causing a disruption by people who prefer the image of everyone holding hands beneath the rainbow. Biologically they still exist but culturally people don’t want to rock the boat.

No, only Frankfurt School Marxists were into this stuff until they managed to (through some mechanism, probably jewish control of the media) break out in the later 1960s and start effecting the libs.

Then what determines which fringe causes confer status, leading to their entering mainstream discourse? How come it’s only stuff Jews love, like racial integration?

I once read that when Jacqui Kennedy was First Lady she did some horseback riding which was covered by the press, which led to picketing of the White House by a fringe group demanding her horse’s privates be covered next time with a diaper, because the public display of horse genitals was indecent. (That’s a true story, I did read that: not making that up.)

How come adherence to that particular fringe group didn’t confer status at the time, followed by the need to put diapers on horses entering mainstream political debate?

How come only stuff like ending segregation confered status at that time, and only that entered debate (exactly the stuff Jews adore)?
