I would divorce the theory of evolution from the Darwin family. There was no ownership of the theory any more than by Wallace or Huxley. All made observations and made a hypothesis that became a theory that has and will change in many aspects. All of the men made mistakes and had their own set of values. Interesting history but not central to today’s science.
Eugenics was and is a horrible set of ideas and practices. Like AGW today, men twisted science to justify their politics. Their experimentation was ill informed and twisted by racial and ethnic hatreds. Much of what Sanger did fit with her racial and class bigotry. Like others she used and twisted the science of the day to fit. Good grief, so called scientists counted bumps on people’s heads and measured skulls to support preconceived prejudices.
Today’s science is in danger of similar misuse. Only good science will out bad science. Already the politicized “scientists” are moving to climate change over global warming which is a move in the right direction. I’d like to see a well controlled study of just what happens to the co2 we are putting out but as long as worshipers of Gaia prevail, that isn’t likely.
Today’s moves toward euthanasia and population control by abortion have more to do with utilitarianism than science. Stalin and Mao produced their own perverted religions to justify their killing and we are moving closer to that religion — Marxism.
Why? Is there some sort of 'good' Darwinian evolution and 'bad' Darwinian evolution?
