He reminds them of themselves because he has all the same "qualities" as them. He normalizes autocracy, xenophobia, sexism, racism, moral and ethical hypocrisy, and those are standard "qualities" of conservative Americans.
Because legacy, independent, and basement medias are constantly beaming images of Trump at them, and when they're given no other option of ideas that's the only one they know. That's why I find it hard to believe that Trump is a Russian asset, then it would mean the media is also owned by Russians, but they're not, they're owned by Western billionaires. Trump has been engineered by the ruling class, and so has his popularity.
Ding!! The ruling class used Trump to weaponize bigotry.
Whats fucked up is as I've watched all of this unfold, I can't help but briefly entertain the idea that those fuckers all decided to do their own version of Richmond Valentine's Plan from Kingsman:
When you get a virus, you get a fever. That's the human body raising its core temperature to kill the virus. Planet Earth works the same way: global warming is the fever, mankind is the virus. We're making our planet sick. A cull is our only hope. If we don't reduce our population ourselves, there's only one or two ways this can go: the host kills the virus, or the virus kills the host. Either way...
I think that when a person with a relatively normal level of intelligence hears the word salad that Trump routinely strings together, their response is usually along the lines of: "What the hell is that idiot saying now?"
But when a MAGAT hears him speak, they think: "Well shit. I can't understand what he's saying, and I think I'm pretty smart, so he must be a genius!"
A lot of people have explanations based on rational reasoning, like if they see the same facts that we do, but reach different conclusions. But these explanations always come off feeling a bit, I dunno, wobbly. What if it's not rational at all? What if it's a form of brainwashing, or something like hypnosis?
