> In the 70s people were saying that we needed to commit brutal oppression against a large portion of the world based on geography in order to prevent future catastrophe.
Erlich (and others) said that we needed to do the following
* programs of mass sterilization in the third world
* a "triage" program where we partition the third world into "savable" and "unsavable" zones, block all movement between these zones, and expel the unsavable zones from our world order such that they will simply all starve to death.
I kinda think this answers the question as to why these ideas get a pass: they offer a way to be racist and advocate racist eugenics policies without admitting you are racist, even to yourself.
I see racism in the population collapse panic too unfortunately, at least in the popular discourse around it. Overpopulation was always about too many of the “wrong” people while underpopulation is about not enough of the “right” people.
What is this referring to?
