If folks let it slide then it just encouraged more of it now. Gotta draw that line in the sand.
Imagine almost any other social hot topic (gun control, illegal immigration, abortion, #metoo, voter fraud, body positivity, child labor, etc) being discussed in such frank and open ways.
You gotta code that shit. Like Tanis Half-Elven in Dragonlance, clearly a metaphor for mixed race or mixed class kids, accepted by neither side, having to forge their own way. THATS how you bake yer ideology into fantasy! Star Trek does it all the time as well. You NEVER go full retard on this stuff!
