I have to say, I find that a pretty inferior, not very well-thought-out response. Who is it you are suggesting should stop doing this "creating people like this?" And how do you put it into effect?
I can't answer for
@Twilight Hue, but I think that many of these people were "created" by the culture we live in. That is, a confluence of cultures, both past and present, along with an idealized view of U.S. history and a belief in the traditional mythos of Americana, in opposition to the more progressive, liberal, and egalitarian ideals which have taken hold over the past 50-75 years. Then there's the actual reality which people have to deal with on a tangible level, every day - and it's rare to find that practical reality really matches up with the abstract ideals people embrace.
In practice, it leads to a society and culture with a lot of mixed messages, inconsistencies, double standards, hypocrisy - along with a general sense of corruption in politics and a good deal of angst, cynicism, and malaise among the masses. I believe the masses overall can tolerate it as long as their basic material needs are met. I don't really believe that things are
that bad yet, though I don't think we're really out of the woods yet either.
Whatever dissension may be taking place - whatever or whoever it is that might have been "created," I don't think it's
really about a dispute over the vote count in the 2020 election. That may be some kind of symbolic rallying cry they've latched on to - and maybe many of them sincerely do believe that Trump actually won and the whole thing was a fraud.
As far as that particular thing, I don't think there's any way that anyone could "deprogram" or disabuse them of that notion. But that's not really the issue. The underlying issue is conflicting visions and ideals for America, which has been an ongoing issue for a very long time.
As to your question about how they're created - or more to the point, how they can become enamored with various bizarre and kooky conspiracy theories - it's that for some people, their vision and ideal for America has somehow gone sour or turned not up to expectations. Whatever people might have been taught to believe about patriotism or the "American Dream" or whatever idealized mythos they've latched onto, some people have found disappointment in one form or another.
Part of the problem is that, up until recently, each generation of Americans would improve to varying degrees, in terms of standard of living and economic mobility. Even despite downturns such as the Great Depression, by and large, life has improved generation by generation for Americans - until more recent times when things have become more stagnant. And now, with the pandemic, supply chain issues, adjusting to climate change, etc., some people are saying this is "the new normal." We're not the land of plenty anymore, nor the land of opportunity. We've outsourced our industries so we can't even make our own toilet paper anymore. Our healthcare system is an overpriced shambles, which in practice is a living experiment in Darwinism - where only the wealthiest and the strongest survive.
I've noticed a general attitude of impending doom, even as subtle as it may be expressed. It's sometimes passively expressed as "well, this country is going down the tubes" or "to hell in a handbasket." It appears we once had a good thing going, but somehow, it went south. Many people just don't understand why, which makes them confused and vulnerable to politicians like Trump and notions that things are going bad because of some "enemy" conspiring to destroy them.
