It's unfortunate you're being downvoted, because I think in many ways you're right. People -- especially people who hold strong views on divisive issues -- usually will not change their minds when presented with new evidence[0]. They're swayed by emotional appeals that get them to change how they feel about an issue.

Sure, there are exceptions, and some people can be dispassionate enough to weigh evidence and change their minds, but that is definitely not the norm.
