The majority of any population (not just USA) are ignorant about most topics. Masses are not intelligent. This is particularly true of a range of topics, from economics and financial domains to anything in the sciences and engineering. The masses are also really bad at being intelligent about anything that requires a long term view or planning.
Given that, it is probably fair to say that the intelligent people are likely not where the majority opinion lies. Not always, of course, there are no absolutes. Being outside the majority generally requires applying critical thinking and sometimes a lot of work to truly understand something. My mother used to vote based on who she liked. I mean, quite literally, not much different from a beauty contest. If she liked the person --for whatever reason-- she voted for them. I loved my mom, but her voting was ignorant and likely damaging to society. I hypothesize, based on conversations, that most people vote this way (or straight-up party affiliation, which is equally stupid).
As an example I use the work I had to undertake in order to understand something seemingly simple: The reality vs. the fantasy of photovoltaic solar energy. I was 100% on the fantasy camp when I built my 13 kW array. It didn't take long for me to, as an engineer, start asking questions based on what I was seeing. The full understanding took an honest evaluation based on actually having skin in the game, experience, math and more. It probably took me a couple of years to go from being a solar energy cult member to being a solar energy realist. I venture to guess that 99.9% of people will never take that journey.
If understanding that the masses are wrong makes one "extreme", so be it. These days we find all kinds of ways to denigrate and stomp on people who don't push accepted narratives. The masses don't realize that politicians create divisive narratives with the sole purpose of capturing votes and retaining or growing power. They do not --regardless of party-- work for us. They work for themselves. They work to stay in power. That is, in CS terminology, their fitness function --what drives their evolution and actions. Their power is evidence of just how stupid populations have been over the years.
On a much darker side, this statement out of government --any government-- is scary in ways history has shown us time and time again. Genocides have been perpetrated because the masses --ignorant and stupid as they are-- are easily manipulated to fall in line with the politics of the those in power. The Armenian, Jewish and Darfour genocides are just a few examples of this. Mobs are not intelligent. We should actually embrace those who do not agree with the majority, not expunge them.
