I'm sorry, but that comes off as semantics. Your argument seems to be that everything is political, it's just that recent history is more contested than earlier history. Which is a statement that I, and most people would agree with, but you seem to be objecting to the use of "political" rather than "controversial."
Come on, you're smarter than that, and I've already answered that question in this thread. To reiterate what I've already said near-verbatim, no-one is seriously suggesting that politics be removed from history, that's insane. When people say "keep politics out of the classroom," it's referring to real-world politics influencing it. If you want an example of this, you can check the DeSantis Guardian article link in the AntiWoke thread as politicization of a subject.
If you're questioning the contentious aspects of modern history, again, all I can is be as factual and as neutral as possible. And I get it, what's "neutral" to one person may not be "neutral" to another, especially if the people both have a stake in said history. I don't think it's possible to teach history without pissing at least one person off, that isn't to say the effort to be made. If a teacher's doing their job well, they'll present the facts, answer questions as honestly as they can, encourage class discussion, and set assignments that allow numerous points of view to be put forth (cliche example, I know, but the question of the Treaty of Versailles and whether the terms were justified or not).
