This is what intersectionality is supposed to be about: the notion that privilege and discrimination aren't one-dimensional, but are complex products of many intersecting and possibly conflicting experiences, attributes, and contexts. Unfortunately this is a very nuanced idea, and we hate nuanced ideas -- especially about people -- because they require time, energy, rapport-building, context sensitivity, holistic thinking, and the ability to grab hold simultaneously of opposing ideas. (And worst of all for some, they require cutting off a supply of intoxicating self-righteousness.) None of that is going to happen in a one-hour workplace training session. If it's going to happen at all, it's going to unfold gradually over a lifetime. Since timelines of that scale are intolerable, we end up with the sort of ham-fisted oversimplifications you've experienced.
