By the way, eugenics was an idea that was very attractive to Rockefeller and Ford foundation as well. The driving force behind eugenics was a man by the name of Charles Davenport, an American biologist. He was the first President of the International Federation of Eugenics Organizations in 1924.
Wikipedia:
In 1932 Davenport welcomed Ernst Rüdin, a prominent Swiss eugenicist and race scientist, as his successor in the position of President of the IFEO. Rüdin worked closely with Alfred Ploetz, his brother-in-law and co-founder with him of the German Society for the Racial Hygiene. Other prominent figures in the Eugenics included Harry Laughlin (United States), Havelock Ellis (United Kingdom), Irving Fischer (United States), Nazi Eugen Fischer (Germany), Madison Grant (United States), Harvard boy Lucien Howe (United States), and Margaret Sanger, (Atheist) (United States, founder of Planned Parenthood).
All this before World War II.
Of course, you are correct that environmental issues should never be allowed to become identified with one political party and that being an environmentalist does not make you a Nazi.
However, there is no question that environmentalism has a fascist problem, which has grown by leaps and bounds over the last 20 years, all the way to even politicizing the weather, and this needs to be checked. Gone are the good old days of racist environmentalism, but now we have a general all around anti human environmentalism, which could potentially turn out to be worse if they continue to grab more and more power over our own private land and commerce, and this on top of what they basically already own through the nationalization of the land in BLM, national forest, national parks, etc. They already own half the west for crying out loud, not to mention the millions of acres in Alaska. Stormwater rules are ever becoming more strict, and the carbon emission cap and trade scheme will be the final nail in the coffin. The enviro movement needs some humiltiy these days. It has become the 800 lb green gorilla in the room that no one wants to talk about.
