> how on earth did the issues with this not become obvious for the team?

I haven't reviewed the context of all 28. But if "the team" were trying to do this rationally: perhaps they'd use census data to weight human characteristics and roll 28 dice. We might not expect more than one of 28 to end up as "queer black mom" but it's not necessarily "woke bait" or "rage bait" for one of 28 to land on those squares. Perhaps it was a logical way of assigning traits?
