When is it ethical to end another human being's life? When is it ethical to discriminate against someone based on skin color, even if your intent is to address past discrimination against people based on skin color? When is it ethical to force people to comply to a mandate when it is clear it serves no societal benefit?

I wonder how much "ethics" have to do with progressive liberal ideology and how much it is about controlling societal behaviors. How is the idea of "political or woke" behavior even remotely ethical given how it constrains personal freedom?
