The problem isn't the PERFECT ARGUMENT, it's the argument that doesn't look like an argument at all.
Take anti-vaxxers. If you try to argue with the science, you've already lost, because anti-vaxxers have been propagandised into believing they're protecting their kids.
How? By being told that vaccinations are promoted by people who are trying to harm their kids and exploit the public for cash.
And who tells them? People like them. Not scientists. Not those smart people who look down on you for being stupid.
No, it's influencers who are just like them, part of the same tribe. Someone you could socialise with. Someone like you.
Someone who only has your best interests at heart.
And that's how it works. That's why the anti-vax and climate denial campaigns run huge bot farms with vast social media holdings which insert, amplify, and reinforce the "These people are evil and not like us and want to make you poor and harm your kids" messaging, combined with "But believe this and you will keep your kids safe".
Far-right messaging doesn't argue rationally at all. It's deliberate and cynically calculated to trigger fear, disgust, outrage, and protectiveness.
Consider how many far-right hot button topics centre on protecting kids from "weird, different, not like us" people - foreigners, intellectuals, scientists, unorthodox creatives and entertainers, people with unusual sexualities, outgroup politicians. And so on.
So when someone tries to argue with it rationally, they get nowhere. The "argument" is over before it starts.
It's not even about rhetoric or cleverness - both of which are overrated. It's about emotional conditioning using emotional triggers, tribal framing, and simple moral narratives, embedded with constant repetition and aggressive reinforcement.
