The atmosphere is so heated, and the statements are getting more and more extreme. Let’s just assume Harris wins the election. After a campaign like this, how could you ever have a normal relationship with your pro-Trump neighbor/father-in-law/Uncle/Barber or what ever again?
I think you underestimate both 1) how many news orgs/media spaces/social communities only report on Trump’s successes and democrat scandals and 2) how much of an echo chamber these people live in. Add on a few natural cognitive biases, such as team thinking and discarding evidence contrary to one’s worldview, and you have pretty much the majority of Trump voters at this time.
They are completely immersed in a world where democrats generally are evil and Trump is one of the good guys. Nothing has ever challenged them out of it, because at this point the challenges are just part of the narrative of good vs evil. Whether this changes your conclusions or not, I dunno (dunno whether I think it even should change your conclusion!), but I figure it’s worthwhile giving an accurate depiction of people. Not all malicious and/or super-ignorant, but rather simply cloistered.
