Even this assignment doesn't sound like there was any hostile intent...maybe some seriously ill-thought out execution, but none the less, no hostile intent.
The wording of the assignment tends to "understate" the atrocity that was American slavery.
As the article put it:
"Without the previous PowerPoint slides, the assignment portrays the evil practice of slavery with an extremely mild view," Bunnell wrote. "A person could read just the assignment and draw a very unrealistic view of the true tragedies that occurred. That was not intended. However, intent does not excuse anything."
But I think that lays out a much bigger question, are issues of race and historical gender roles (or any other sensitive subject) so sensitive, that perhaps there's no way to possibly teach it with any sort of immersion technique in a meaningful way that would be conducive at a Elementary or Jr. High level?
Meaning, are the issues so in-depth, and require a comprehension level as such, that there's no feasible method to teach it in a way that a young kid would understand and truly absorb, without bringing it down to such a level of simplicity that it comes across as "trivializing the issue"?
If so, then perhaps they should steer clear of those topics until kids are in the grades and age levels where the critical thinking and comprehension levels have developed to the point where the issues can be explained in a meaningful way.
It's one of those situations where society is going to have to make up their minds...if they insist that social justice themes are going to be taught at young ages in schools, then material is going to need to be catered to what your average 8-14 year old can understand and conceptualize.
That comes in the form of simplistic concepts like "pretend you're in this group" and "if you were in this group of people that bad things happened to, and you had to write a letter, what would it say?"
It's not pragmatic to expect elementary school kids to understand the types of concepts (with the gravity and complexity those topics deserve) that we'd expect from a much older person.
