History is what folks say it is
Unfortunately
We would all benefit from a more comprehensive understanding of that era today
Some nuance in discussing historical events, as opposed to trying to frame everything in terms of "good guys vs. bad guys" or in terms of today's political disputes would help as well. But good luck finding people willing to do that.
We just need to do an end-run-around of the modern progressive historians. That will solve at least half of our problems and almost all of the blame-America ones.
We can use free and open source audio books in the public domain to achieve this purpose.
The old historians were trustworthy, meaning the old historians are useful to undermine the progressive historians of today.
