It’s the dumbest take ever even if you’re just trying to play devil’s advocate, never mind making it an official state PUBLIC EDUCATION POLICY. It’s like saying slaves were fed during slavery that allowed them to live. Technically yes they were fed, technically yes they learned skills, but it’s all overridden by the fact that THEY WERE ENSLAVED. There’s no room to find any silver lining in this situation that could potentially give any props to slave owners because it’s one of the most subhuman behavior imaginable.
