(Not to be confused with amoral): when someone with religious or moral authority over you telling you that you have the "wrong" moral values. However, you can ignore 😉 these people.
If someone calls you immoral, ignore them. When they call you amoral maybe look at yourself in the 🪞 mirror and decide what you may need to change.
