Tolerance of intolerance is not a path to freedom. Choosing to do nothing will only mean that rights and freedoms will be destroyed. Call this the lesser of two evils if you must.
If you let intolerance fester, it will grow and take control, then it will start hurting and squeezing others. It’d be foolish to sacrifice freedom in the name of freedom.
I don’t think the killing them all part is necessarily a motivator. Perhaps more so that solar and wind have become price competitive, and that investing in renewables have the additional benefit of helping China lead in these crucial areas.
