Against the great sin of exclusion (in the name of seeking ever greater human purity and perfection) is the great virtue of inclusion.
Never more so than now, when the Earth and the human race faces an environmental and existential crisis.
We need the help and the ideas of ALL (the 99 % plus 1) to get us through this crisis -- we can't let the fate of the world rest on the unlimited wealth but strictly limited brainpower of just the world's 1%.
Because 'exclusion' was what the Nazis and Auschwitz was all about.
By way of contrast, their contemporary Dr Henry dawson was all about inclusion.
So he made the very biggest inclusive tent and went out and recruited the help of the despised 4Fs of the biological world - the fungal slimes - to produce Manhattan's 'impure' penicillin that saves so many of the 4Fs of the human world and so many human 1As as well.
It was a lesson we boomer kids never forgot.
Modernity's quest for ever greater purity in the most civilized of the human race had led down to Auschwitz while the despised little fungal slimes had produced the great good of life-saving penicillin.
We were post-modernists before we were out of our nappies....
