January 6th is not seen as an insurrection but as citizens banding together to protect democracy. Collusion with Russia was always seen as a false attempt to make him look bad, especially with things like the dossier being faked. Tax evasion is considered smart if you can do it legally, and the New York prosecution for what the industry considers standard practice reinforced the perspective that it was weaponizing the justice system. Autographed bibles are no more sacrilegious than any of the megachurch/televangelist who buys a private jet because God wants him to to.
Each one of those hurtles may take someone out of his camp, but for some that will only be if there is a viable alternative. Keep in mind that the alternative on the democratic side is trying to end their 2nd amendment rights, open the borders to secure a permanent underclass voting block, and lose the national protection of God by persecuting Christians. It doesn't matter to what degree any of that is true, that is the hurtle they have to clear.
Since armed service is venerated more on the right than the left, and has higher percentages of veterans and their children, this might indeed be the straw that breaks the camel's back for some or many. He is grifting in so many areas, that if he is also shown to be a grifter on respecting the armed services in addition to being a false Christian and 1 percenter elite then parts of his base might see him as no better than the Democrats.
And there you go from the moral/intellectual high ground, mocking them as toddlers and saying it's right and normal to laugh and make fun of them.
I can't stand vaccine hesitancy and anti-science bullshit. I've had to deal with this becoming a Fox News thing in my own family, and lost too many people from alternative "Eastern" medicine over "Western" medical science. But the mockery and ridicule only feeds into the Christian persecution complex most of that rural white population already embraces, and causes the wagons to circle.
