Consider that people may develop political responses to what they see in the real world.
Consider the truly bizarre origins of antisemitism, for one. (And I'm not talking about people who have opinions on geopolitics in the ME. Think about how the other kind of antisemite, who doesn't give a rat's ass about what's going on 10,000 miles away reaches their political opinions.)
Or, better yet, the gay satanic-panic currently gripping half the country, and the insane culture war being waged around it. You can't actually believe that all those people who have strong opinions about it have been somehow personally wronged by homosexuals.
But they do turn on the telly to listen to some lunatic screaming about how there's a mass conspiracy to turn their children gay.
Or the satanic panic over Dungeons & Dragons in the 1980s. One of the cops ("school resource officers") in the middle school I went to still believed in that nonsense and it was the early 2000s by that point.
That is believable.
What would be less believable is your lived experience sending you on the crazy train ride that the far right party is currently on. I really can't understand how that can happen without a media bubble, but if it did, I'm genuinely interested.
It's not really alarmist or hyperbolic when some of the newer deranged things include not needing to vote anymore, or annexing Canada and Greenland.
You have to, like, take this seriously. Its not just some reddit troll running his mouth, and it's borderline gaslighting to suggest some both-sides-equivelancy between the two.
