Question

Ethical subjectivism applied on a societal level and arguing that whatever is morally right within a society cannot be criticized by those outside of that society is called _______.

Answer 1

I believe the answer is: cultural relativism
cultural relativism refers to a certain set of idea, principles, or value that should be understood based on the culture where that person is from.
We use cultural relativism to measure the 'good' or 'bad' of the people's behavior based on the culture that they're used to, not the culture that we currently has.
