This is also why my readers won't see any viewpoint characters from, say, the Iltine Union or the Theomachy of Galia. Writing a character from inside their head is an even more intimate experience than reading one.
Sociopath admirals, rogue emergent evil-overlord AIs, crime bosses, corrupt executives, the Fifth Directorate Ethics Committee, even politicians, those I'll do.
But some mindsets are like taking a swim in raw sewage, and those ones I'm only going to show, or write, from the outside.
