Rightoids don't believe in fixed truth and there's no use debating them for this reason. You can see that at shit like unite the right in burgerland where you have jewish zionist kekistanis marching alongside literal neonazis.
It's easier to paper over disagreements when you don't really have ideas to argue about, just instinctual grievances and common hatreds against certain groups that you rationalize.
For the left the reasoning comes first then the conclusions, but leftists differ on reasoning and conclusions which leads to disagreements.
On the right their reasonings are more like rationalizations for why their disgust of LGBTs or anxieties about demographic change or whatever is actually good and justified. And their reasons are a list of rationalizations of why that COULD be true or justified. Rightoid thought is the political equivalent of retconning. Thats why they can shift from le rational skepticism, to libertarianism/ancap, to jordan peterson archetype ideology, to fascism, to whatever. Because they're just reaching for whatever arguments, philosophies, or father-figures would tell them that their inarticulable sense of aggrievement against whoever is totally justified.
What they believe is true at any given moment is whatever would need to be true for them to be right and you to be wrong. They already know they're right, now they just have to find out why, and whoever is the most convincing at any given moment is who they follow in that. That's the basis of all rightoid thought, so they're really all on the same team anyway.
Their disagreements tend to be about interpersonal drama and who slept with who's gf or w/e. Not that that isn't enough.
even boomer neocon thought is based on this sort of post truth shit:

Bush administration who used it to denigrate a critic of the administration's policies as someone who based their judgments on facts. In a 2004 article appearing in the New York Times Magazine, Suskind wrote:Post too long. Click here to view the full text.
