You’ve essentially described meme theory except your blaming the products of memes for the memes themselves. Trump isn’t the cancer, nor is musk or Putin or whoever. They all have supporters and a lot of them. Trumps approval rating is still near 45-50%. And the supporters aren’t something he grew or cultivated.

Trump is the product of a meme. Conservatism isn’t the end point results of a meme, it’s an expression of an underlying cultural phenomenon where after much progress is achieved, people begin to miss the familiarity of the past and wish to stop making progress for a short time.

And so the real thing being spread and what needs to die is the meme itself. And the only way you kill a meme is to change it into a better version of itself. Better meaning beneficial. Whereas what memes naturally do is become larger and more popular ideas until they are out competed by another meme.

You can’t kill a meme by turning conservative people liberal. All you can do is make people better conservatives and help them criticize and improve their own memes. Same way with religion and it’s been happening for millennia for most of them.
