These are all valid concerns. I do certainly agree that Trump is not someone you want in charge of a Social Studies curriculum, given his ignorance and intellectual shamelessness.
Many conservatives recognize that to give Trump the power to control a patriotic history curriculum is the give the next Democratic President the power to make the 1619 project a national curriculum.
But this does raise some interesting questions about whether we should have a national curriculum. Should we insist that all students in the United States have knowledge about certain topics, and if so, how do we pick which topics?
The editorial judgments aren't just about the commercial market, since the people who make the textbooks are going to have to determine what to focus on and why.
It is also worth noting that historians will have their own biases. A big reason Ulysses S Grant has such a poor reputation in 20th Century America is that so much of history was written by southerners.

In politics, it's rare for people to give up power without getting anything in return.
When do Democrats do this?
