I think, way back in 04 or something, it was more like how PCs treat Monster Races, as well, monsters, not people. A gaming trope criticism. Sometime down the road, 2011 or so, maybe as soon as 2007, thst changed more to a basically a reskin of modern political issues. (because the real life political issues have no 'monster' elements, it's not very satisfying allegory for either side of the debate in my opinion)
