Moral persuading goes hand in hand with actual violence to show that you mean business. The moral persuasion just goes to get the common folk on your side so to try to prevent future issues. Look at Malcom x and MLK. MLK wouldn't have got nearly as far without the threat of Malcom X causing actual immediate change. Like open carry laws.

Moral persuasion is a great tool, but alone, enacted zero real change.

Not going to lie, I have no sources to back this up, it's just what I was taught in highschool.

That said, even with both violence and non- violent persuasion, racism still perpetuates within America.
