I’d say any claims about rape being a justification for genocide have lost their weight after Israelis protested punishment of IDF soldiers for rape of prisoners on the basis of “Palestinians deserving it”. There are no moral arguments supporting begining, maintaining or continuing the genocide in Gaza.
IQ tests intentionally omit any questions related to empathy, emotional intelligence and creativity, so it can favour people from the top of the pile and act as accurate perdictor of success in ruthless capitalist society. It implicitly promotes lack of those traits in individuals and explicitly promotes the definition of intelligence that’s unrelated to them. While you don’t get lower scores if you’re highly creative or empathetic person, so it’s not directly a detrimental for society and can be a useful metric for some cases like specific jobs, it’s image as sole measure of intelect is manufactured to promote “specific kind of people”, to which group many republican businessmen would belong.
I’m not disagreeing with what you said, just thought I’d expand on that.
