> Slavery wasn't abolished by changing people's minds via rational debate.
I didn't say it had to be done via rational debate.
> They only changed their beliefs after decades under new laws and culture.
So they did do it after all.
> The research is out on changing people's beliefs, for most it usually causes them to dig their heels in and hate the other side even more. If you encounter a racist person or a Nazi in real life, you will not change their beliefs with rational debate, so don't even try. Just avoid them because they are unpleasant people. You will be happier if you stop fighting this futile moral crusade.
Look at you trying to change my beliefs via rational debate. What a hypocrite.
