Same problem with a lot of leftists too.

Why won't these racist, inbred, homophobic, idiot, sexist, transphobic, breeders, backwoods hicks brainwashed by Fox News, living in horrible flyover states that don't matter and have no redeeming values, these fucking fascist bootlickers, delusional people believing in a fantasy magic sky daddy, these fucking Nazis just realize that we know what's best for them and let us, the people who know what's right, make all the decisions? Better yet, they should all just die and get out of the way. When we get into power you know we'll need to round them up and re-educate them for their own good (note: I've actually seen this bit suggested on lemmy unironically).

So why won't they join us working towards a better world?

It's a problem with a lot of groups of people, really.
