There's the context of Trump riding the wave of right wing rage with his claims Obama was born in Kenya. Shortly after he paid a bunch of hourly extras to form a crowd as he descended a golden escalator to launch his 2016 campaign claiming Mexico was sending rapists, and a cadre of WWE fans, white supremacists, credulous evangelicals, and reprogrammable meatbags who tuned into Fox News decided politics was interesting again.

For most of these people if you start asking which years America was great versus not great they might admit some of the Bush years were sub-par (because of those OTHER people who hate freedom), and preach about the good ol' days when we drank water from a hose. Where everybody treated each other right, unless you were a person of color in a sundown town. They will retcon any facts you present and claim you are cancelling them and it's no fair remembering the past, as they have been conditioned to believe faith is a virtue. The Bible's "Faith is the substance of things hoped for, the evidence of things not seen" fucked up my brain for too many years of my life. I wish it was easier to fix this, but a useful quote I remember when I break off most discussions with my dad is,

If someone doesn't value evidence, what evidence are you going to provide to prove that they should value it? If someone doesn’t value logic, what logical argument could you provide to show the importance of logic? -Sam Harris
