That article is so incredibly biased that it's essentially liberal propaganda.
Oh man, I hope we get a big ol' "what about"ism reply that cites nothing but makes it super obvious you just don't like "liberals."
Let's just talk about the amygdala. Yes, it has the purposes you stated. But it's also the primary component in generating PTSD. Liberals claim PTSD from darned near every kind of emotional upset...conservatives don't.
Liberals get "triggered" by "micro-aggressions" even to having physical reactions far more than conservatives. When have you heard of conservatives requiring their "own spaces" or "trigger warnings" on media?
But you get a drag queen in a library for a story hour, and you melt down. Or Planet Fitness enacts a bathroom policy you don't like, you melt down. Or a pride parade. Or a Planned Parenthood. Or a book with content you don't like so it should be banned.
But sure, let's pretend that conservatives don't have physical reactions to things, lol.
Why is it that liberals disown--can't stand the physical presence--of conservative relatives but conservative relatives can accept being in the presence of liberal relatives? Whose "fight or flight" response is actually overactive?
I think you are confused. First off, this forum is littered with stories of people disowning kids who come out as gay, non-Christian, who live with a partner before marriage. People who'd never go to a family member's gay wedding, who would disown their daughter who got an abortion. On this very thread is a person who becomes apoplectic at the idea that their child could marry a person who's divorced or has a child and the consequences they'd face from them for choosing a partner they, as a parent, don't approve of (and the only people they approve of is conservative right). Some of the right is so fragile that owning a bakery and making a gay person's wedding cake is just too much. The difference is you rebrand these behaviors as an issue of morality, not politics or political ideology.
So ignoring that icing people out for political ideology is not a "liberal"-only practice, and that you're just repeating nonsense you've picked up from "news" agencies that appeal to your political bias, and that just a second ago you were complaining that people are too fragile before going on to complain about people not wanting to hang out with you... The people I know who don't talk to their Trump-voting relatives? It's not simply because they voted for Trump. It's because their ideology, their behavior, or some combination of the two makes hanging out with them undesirable. I only have one family member we've all kind of given space to, and it's not because she voted for Trump. It's because she has made voting for Trump and repeating absolute nonsense the whole of her identity. She talks about blackwashing, forced gender reassignments of children in public schools, the gay agenda, drag story hour, the "right to life," the intellectual elite and liberal radicalization in colleges... It's exhausting, it's nonsense, and she says it to wind people up. Since its the WHOLE of her identity, she launches off on these diatribes in private, in public, and it's embarrassing to be associated with that.
I could care less that she voted for Trump, but I don't want to hang out with somebody who says that white people are more oppressed than black people and she won't let her kids have a gay teacher because he's probably a pedophile, and basically just a torrent of things that are just stupid. I'm in my mid-40s. My time on earth is both valuable and short. Unless I'm actively collecting a salary to associate with people I find to be a chore to be around, I don't particularly feel like I should have to.
And what has happened when people switch positions, becoming more conservative or more liberal?
People do it all the time. Everybody in my family, except for me, has done it. My husband used to be a deeply conservative Christian with all the far right ideology. No abortion, no gay marriage, no welfare... Literally all the things. Now he's wildly far left. Pro-choice, pro-gay rights, pro-trans rights, BLM supporter, the works.
Or how does age matter, in that people tend to become more conservative as they get older.
They don't. People typically remain about where they were their entire lives on the political spectrum, but if they are going to change, they're more likely to be liberal going more conservative vs conservative going liberal, until 2015, when a spike showed people were more likely to become more liberal as opposed to conservative, then a huge spike of the same in 2020. I wonder what happened those years that drove people away from wanting to be a conservative republican? LoL

If you looked at the actual research report, that presented no such strident claims. It pointed out the weaknesses of its test methods, particularly in determining just what "liberal" and "conservative" means in medically verifiable terms.
That's now studies work. They point out areas of fallibility for future analysis and contextualization. It doesn't mean the findings are incorrect. It means the parameters for study performance has been articulated.
