CMV: People will never change their view if you call them ignorant or evil.

From what I see in politics, there is a big emphasis on convincing the common voters that the opposition is evil or ignorant. 

I have never heard a story of a Nazi or white supremacist that has changed their view because the media and everyone they knew repeatedly called them evil.

Changing people’s minds is more about convincing them why the other side is better rather than demonizing the side of the person you are trying to convince. 

I see many people, especially in American politics, that a majority of people either try to say their idea is perfect with no flaws and people are idiots for not having their ideas implemented or say if you disagree with me you are ignorant and evil.

I just wanted to know if there was an merit to that strategy and why people do it even if it is in a sense immoral.

Edit: White Supremacy and Facism were just examples. I want you to argue for doing it for real world issues like socialism, abortion, gentrification, taxation, immigration, etc.

It might not be about changing the view of the hard-core evil person. They've got their own self-justification for their way of thinking and they think they're right and justified.

It's more about labelling that way of thinking as being socially unacceptable so that other people who may be toying with adopting it don't take that path.
