>>52699133>or even just responding to the horrors of the 41st millennium in a rational 21st century manner
Which in the case of the Tau it worked spectacularly as they are prosperous and thriving. The Tau outlook in alien relations have netted them friendship and allegiances of hundreds of species/races. Sure there has been a few hiccups like with the Dark Eldar, Orks, and Nids but the vast majority of the races that the Tau met are not inherently evil or hostile. So they are justified in pursuing their way.
It's only when the Tau had Imperium ways rub off on them, becoming belligerent and militant in response to the Imperium brutality, did they start to suffer.
So all I am seeing is vindication that 21st approach is the best in the gromdark.
