How many iterations will it take for them to just say what they're really against: policies that promote empathy and compassion for people who are different
That's the ironic part. Even if we went back to 1800 the vast majority of these angry people wouldn't be slave owners because they wouldn't be able to afford it. They'd actually be far more likely to be debt-slaves than own any people themselves. The era they actually want to go back to is an idealized version of the 1950s, when you couldn't own people but you could call them slurs in public, they had separate drinking fountains, and they lived far away from you. Plus you could hit your wife if dinner didn't taste perfect, physical and mental abuse was how kids were raised (when you saw them at all), and one income could raise a family.
Sad how those last six words are the only thing we could agree on and should actually get back to, but it's cheaper for the owner class to stoke hate.
Also you could either shame/harass LGBTQ people into suicide or just casually murder them yourself. And if you had a baby with obvious disabilities, they would be whisked away to an asylum for life and you'd never have to think about them again. Ah, the good old days!
