Interventionism? I know what intervention is, if you are talking about some philosophical idea, then I don't know, and I'm not going to look it up to clarify. Look, you treat others the way you want to be treated, others may do the same. The way you want to be treated is going to be different from the way someone else wants to be treated, so you will each treat each other differently. This can lead to misunderstanding and hurt feelings. This exact thing is why shared cultural values are developed, and why laws are instituted. People value different things, so there will be variations on what individuals within a society see as cultural values. The law is established to make it as clear as possible what behavior is acceptable and what is punishable and how. Just laws balance between people's rights and freedoms. Cultural values can influence law formation. But the fewer the laws, the better, if you care about freedom, and if you care about freedom, you voluntarily do as little to violate the rights of others so that new laws aren't passed to limit freedom.
