It never fails to surprise me how Trumpers continue to undermine the efforts of those who would see the nation become whole again.
Maybe if you avoid the dismissive term "Trumpers" when referring to people, that might be a step toward what you want. Another step would be respecting to their concerns and allowing them to have a voice. Kind of like a civil rights movement, but for people with different ideas rather than different skin pigmentation.
As they say, if you want to change the world, start with yourself.
I never blamed the man, be it Obama, Trump, Biden or anyone else they send along. (Though the North Korea level adulation of Biden is unique among developed nations.) They represent a certain faction of people, for better or worse.
Nobody except a few fringe groups want the country to fall apart. Such groups from both sides should be handled the same. Those in the middle have different views, but one part of those in the middle keeps insisting that he other part is motivated by racism or stupidity. Until that stops, there will be no united nation.
Call people white supremacists for 4 years and suddenly want to be friends? Reminds me of Kamala Harris, when asked why she flipped from calling Joe Biden a racist to being his running mate. She gave that laugh she always gives when she is caught out, and said those were just campaign words. They feed the poison to the public, and don't mean of word of it.
