So "revenge porn" is bad because it hurts people's feeling
No, because it is harmful. It harms a person's reputation. It also violates a person's privacy.
But cheating on someone shouldn't be criminalized even though it hurts at least as much
This is a false choice.
Society has decided that punishing people for cheating is a stupid idea. Society has also decided that punishing people for tax fraud is a good idea. These things are both completely irrelevant to any laws on revenge porn.
