While I agree with you, I think the point made by OP is simply that everything is subjective. What is "good" and what is "bad" is subjective. Not everyone on earth will have the same definition.
That’s the first line of the article. I don’t think it’s really subjective to say that killing women for driving cars counts as treating them badly. (Unless you just want to make some kind of general philosophical point about everything being subjective, but how would that be relevant?)
