Hitler knew that there were plenty of Germans who were antisemitic, but the societal norm was to let them be, and take advantage of their skills. So the stereotype of the Jewish financier, lawyer, doctor, helped them to survive in spite of the antisemitism. Hitler didn't think that societal norms could be changed overnight, but he knew that if he could help people to convince themselves that "Jews were the problem" then he would have the public's support. Over time he found numerous ways to make Jews the evil he thought they were appear so to the public, and then it was no big step at all for the German public to be complicit in support of "The Final Solution" in little and big was throughout the Reich.
Now we have, in 21st Century America, evangelicals supporting the most unChristian acts by people in government, or closely allied with it, that if they were able to reverse what they see and realize how they would react if the perpetrators were Democrat, they would not be fooled. But they aren't able, the blinders over their eyes put there by their "MAGA" hats seem immutable for now. Those MAGA blinders were put there by the desire to see change in D.C. and so, like the promises by populists before, the people are willing to believe that:
-Abortion will be banned. This is their overarching hope. There is no compromise, no alterations in Roe v. Wade, only reversal. There are no extenuating circumstances. This is the cause.
*If Planned Parenthood and all its services for women's health are to be sacrificed because of the small percentage of abortions, so be it.
* Never considered is that abortion could be reduced greatly by a fully funded women's health system, one that makes one good choice more likely: to carry a child to term because it will likely be healthy, and there will be financial aid for as long as the mother needs it, ensuring that the child will not be raised in poverty. Or another good choice: to carry a child to term and put it up for adoption, because the mother will have all the health, spiritual, and financial aid she needs to get her through that time.
- We are going to build a wall, and Mexico is going to pay for it
*This has the appearance of happening, but it's not. Mexico's President has stated very clearly that there is no way for them to be forced to pay for a wall, and a significant plurality, if not majority, of Americans would rather have our bridges made safer, or our health care made more stable.
- Muslims are the personification of evil, though the evil be perpetrated by a relative few who have twisted Islam to their own purposes, they should all be held responsible, and kept out of this country, and even made to leave if here already.
*Yet domestic terror perpetrated by neo-right extremists is on the rise,

- the announcement early on that the American Dream is dying, and he's going to fix it.
[“The American Dream is dead — but if I win, I will bring it back bigger and better and stronger than ever before.”— Trump, announcing his candidacy in June 2015.]
*The main thing that has happened from "MAGA" is to put it on hats.
American evangelicals have forgotten this:
Confirmation bias is total, for the American evangelical Christian.
