I get where you're coming from and why, I really do, but I think saying stuff like that is really unhelpful.
I'm about as left wing as they come, but I grew up in rural Florida. All the bullshit you see about the place? That's my family. None of them specifically have shown up on the news, but still, it's them - their beliefs, attitudes, etc.
The issue isn't deception or manipulation from regular conservatives. When my grandparents / cousins spit out that sort of bullshit, that's not what's going on.
The issue, rather, is a complex one that is, among other things, a thing of trust.
They believe, honestly and truly, in Fox News. They believe in their preachers. They believe that homosexuality is a demon that possesses people, and by interacting with "the gays," you "open the door" to demonic influence in your life.
That last bit is an example of something I was outright taught.
When my grandparents talk about how it'd be good for America to round up all the gays and put them in concentration camps, what they're feeling is protectiveness. They want to protect people from Satan's influence, and if someone has accepted the enemy to the point of being proudly gay, then why should people be sympathetic to them? Get rid of them all, obviously.
Yes, it's insane and hurtful and stupid and so frustrating that I haven't spoken to my extended family in a few years.
But they're not trying to trick people. They don't need to think about what they believed before, they don't need to second guess what's right, they know what's right. What's right is believing in the authority figures they've been trained to believe in. What is right is to listen, to obey, to fight as they are directed to fight, for the good of all.
It's horrifying from the outside, but from the inside, it's a safe little bubble where you don't have to wonder and worry about what is the right thing to do. It's easy - the only hard part is acting on it. Do what's right, and everything else will fall into place. It's simple and feels good.
To challenge that way of thinking, to suggest that they have to figure it out themselves - that's a huge ask. Going against what they've been taught their whole lives, and for what? To have to deal with moral uncertainty and unsolvable moral dilemmas? That's hardly a reason to change.
