No, they aren't haters. They just express common sense.
It's fact, that 42% of Americans are workers without High School or University cert. They lost their jobs (starting in 70s) when many US factories and companies left US for cheaper productions. And it's a shame for those Americans being without a job and poor social support. These are Trump's voters. Not the intellectual elite for sure. Harris's mistake was not to speak to these lost workers.
Also it's fact that the average IQ is far below 100, with means, that the 42% are really got a very low IQ.
And this is apparently to see here on AN.
