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 it really started with the Clinton impeachment, Rush Limbaugh, Fox News, then we had the stolen 2000 election, then 9/11, wars in Iraq and Afghanistan, “support our troops”, anti Muslim rhetoric, then the rise of social media. All coincides with the brainwashed kids/boomers who came out of the heritage foundation. Obviously, the racism and conservatism was always in the background. You could even trace it back further to Regan/Nixon/McCarthy.
You can trace it back as least as far as Barry Goldwater and the rise of right-wing “think-tanks” in the 1960s which came as a backlash to the civil rights movement and the perceived dominance of left-wing politics in government. Which led to Nixon’s “Southern Strategy”, right-wing talk radio, Fox News, and the ongoing brainwashing of much of rural America in particular.
