The Problem With Zero Sensitivity for Morality

I feel like there's no sense data anywhere to resolve any sort of moral disagreement. Like if I take a mathematical truth, like one plus one equals two, I can actually have one and one things and then put them together in seat two. The argument is mathematical anti-realist. It's like math has an uncanny ability to line up with reality or something like that. But but yeah, but you can argue it's a little bit harder.
