Polarized. Two nearly identical people can easily be convinced to hate each other over all sorts of silly nonsense because of what media they choose to consume.
Nah, if you're so unhinged that you're making death threats simply because someone referenced objective and observable scientific facts that your warped fairy tale reality doesn't let you accept, there's no "once you cut through all your regressive, batshit beliefs, we're really the same". There's no reasoning with them because the delusion (e.g. "owning the libs") is their whole identity.
I've learned that trying to take the high road with people that revel in bigotry and corruption is a fruitless endeavor. I'm done being naive and giving them the benefit of the doubt. Perhaps that's because I live in the real world and actually deal with these people, rather than the pontificating about the intellectual concept of these people.
