Judgement can be made based on reviewing the effects of decisions over time. We need a dynamic system of laws and legal review that is capable of correcting for mistakes and adapting to new challenges.

I agree that we do need a system, that not tolerating intolerance is a good basic principle, and that such a system can be functional. I don’t think it can ever be perfect, because people aren’t perfect, but it can be a lot better than nothing.
