After many long discussions, I can only conclude it less about the values of the supporters and more about their psychology.
His supporters want whatever he wants, as long as it means that the right people get bullied. There's not much deeper thought than that.
It's very sad to see people that I respected debase their own principles so that they can remain proud Trump supporters. Their identity appears tied to the decision, and I know only one person who had the principles to to respond to any of Trump's actions with "OK these people actually have no clue what they are doing." (Which was in response to their treatment of Zelensky in the Oval Office).
