This is a feature, not a bug. Casuistry is the science of determining the correct course of action in a complex situation. It’s complicated because the world is complicated. Attempting to create a moral system from first order logic (deontology) or a linear system (utilitarianism) was doomed from the start.

Which is trivial: pro-life vs. pro-choice, free-speech vs. anti-harassment, etc. I don't think there's anyone on any part of the political spectrum who thinks their ideas are not virtuous.
