Income Tax, Popular Senate, Women’s Vote Amendments were all communist machinations. (The fellow travelers did not care about women anymore than they cared about blacks; they cared that 50% of the population could then be reliably used to vote left far more greatly and far more consistently than the male 50%.)
Having said that, I agree with you:
Both the Civil Rights movement and the Global Cooling/Warming/Changing movement are Redistribution schemes on a very grand scale.
Since CR is national while GC/W/C is international, I reluctantly choose the latter as the winner.
It is a tough call.
