Eugenics has always been about genocide against the other. I honestly think if birth control was only available for colored people then conservatives wouldn't have a problem with it. Abortion too. Liberals and even well meaning progressives will sometimes fall into the trap of pitching abortion and birth control as a part of the solution to poverty. Not realizing that they're actually saying the poors aren't allowed to have family.
Edit: I don't like how I worded this but I'm also finding it hard to express what I've observed and the problems I've noticed with it. I'm very much for access to birth control and abortion for everyone. The issue I have is when people want to discourage people from having kids if they're not wealthy as a part of solving poverty. And somehow I get the feeling that the bar is often high for low income black and brown people. Like the aspiration towards progressivism is there but there's still some unchecked racism and classism leading towards support if eugenics. Not to mention I see a lot of support for out and proud eugenics against disabled people and neurodivergent people.
