This has never been about political discourse, a navigation plan for the country or creating the best society possible. Not for Trump followers.
He was a base and unsuccessful businessman with an equally chaotic personal life when he first ran. He'd been a longtime Democrat until it served his purposes to be Republican. Nearly each issue he touches on that isn't about fraud is a polar opposite to a viewpoint he's expressed in the past. He can read, can't write, can't critically think and knows only hurting others to make himself feel big. That was the choice. That was the one they went with.
No one expects great things from a leader like this. They expect brotherhood and fortification of their own outlier ideas. It's really no different than a disenfranchised youth finding a violent extremist party online. It's the desire to be known, understood and included. The ideology is unimportant.
Trump is criminally accused, legally guilty and thoughtless in his aggressive and childish behavior. Following and defending him now is to make a clear, considered and obvious choice to support bigotry, hate, exclusion and sane ideas. There's no defense that squares that. Conservatives have been out of ammunition for a long time now and they've been reduced to hurling rocks blindly at things in the night. They don't want freedom and democracy; they don't seek inclusion and application of Constitutional rights across the board, they viciously mock those whose stand for freedom dares to be different than theirs. They end up hating the very things that democracy implies in search of something 'other,' something just theirs, some kind of group identity umami that will elevate them finally above all the forces and people who've kept them down for so long.
To defend behavior with utter lack of principles is to be unethical. To mock and belittle others just to feel better is being a bully. To tell others what they don't deserve and assert only that which makes oneself happy is to act entitled. To deny others what, in their position, you would most need in the world is a cruelty beyond redemption. You get ot be human here once. You might want to consider what you leave behind for the world that had enough room and resources for everyone.
