We've simply had decades of propaganda teaching us that the US is the most moral nation that has only fought moral wars for moral reasons.

A lot of the history books are about American exceptionalism and triumph. Even when they cover topics like slavery and civil rights, they paint it as being temporary embarrassments that we got over and now everything is OK.

MAGA is just a bunch of people who swallowed that propaganda whole and never questioned it in the slightest. We can see that in the fact that they get really upset about history lessons that are even slightly critical or analytical of America's past.
