Okay so I will come and kill your family in their sleep and make you a slave because it is morally acceptable to you.
Have a good day.
Edit: Obviously I’m just teasing, but this is to give you a practical example.
Moral relativism is a great evil in our time.
I know, I understand that but it’s important to talk about it, it’s the only way we can understand and be understood and protect ourselves from misunderstandings.
