I also think the reasoning in this example is bad for general reasons, namely moral heuristics don’t behave like scientific theories: falsifying a moral hypothesis doesn’t mean it’s not worth considering.
Then again, the same applies to scientific theories, so long as the old now-falsified theory is a good approximation to the new currently accepted theory within certain ranges of conditions (e.g. classical Newtonian physics if you’re much bigger than an atom and much slower than light).
