I approve 100% of teaching this. Historically accurate discussions around the treatment of native americans, blacks, and immigrants should be had and brought to light. The curriculum should be updated with facts that are relevant from all sides of the issue / occurrence so it can be represented consistently by instructors. With those facts, the student can then make a decision about how they feel about it, the amount of empathy they choose to express, and if it's something they want to explore more. That said, I would would drop the CRT attachment at this point as it's essentially a nuclear term.
