I'm from there. Many people there genuinely believe Mississippi is a better, safer State than most others in the country. And they absolutely believe Trump is saving the US from the liberals.
I cannot stress that enough, they actually believe progressives have been ruining the country since the 90s and that conservatives have been trying to save it.
Many people are so indoctrinated or poorly educated, or both, that they think you're the one who's ignorant or spreading misinformation. In my experience, at least.
