Freedom from Sanity
It seems you intend this as a counter-"gotcha" to my alleged "gotcha questions" as you deemed them, because you don't seem to distinguish between issues that are genuinely contentous within both society at large and the historical profession in specific (whether dropping the atomic bombs was a good thing, all things considered) and issues that are essentially settled and only considered controversial by people who oppose the accepted mainstream position (whether the Nazis were bad, whether slavery was wrong) or historical facts that are settled but opposed by people who peddle blatant lies (the Civil War wasn't about slavery, the Holocaust never happened, there was no genocide against Native American populations).Opinions are opinions. It is my opinion that if the facts are presented in a straight forward manner the student should be intelligent enough to come to their own conclusion.
Your two examples are basically "gotchas".
For example would you have a problem with telling students that the use of the atomic bombs were right or wrong?
With that said, while I wouldn't have a problem with teachers asserting what is clearly a consensus opinion in the historical mainstream, for more contentous issues like the atom bomb, I would suggest presenting students with historical arguments in favor and against. This would have the advantage of fostering critical thought and argumentation, while still presenting students with a near-accurate understanding of the historical issue.
