I've clarified a few times here, it's not a stance I have, just one I've seen and saw as tempting enough to ask about. Their logic goes, if A) nuclear assault is a step above normal warfare, and B) normally all countries/ethnicities/cultures are equal and not below one another on the basis that that we all have equal potential both good and bad, and C) we live in a world that found a way to justify witch hunts, the red scare, and cancel culture, then D) a country that does engage in nuclear strikes would (according to the logic) mark a civilization as being humanly lower than other peoples and thus it wouldn't be unfair to have a cancellation-or-red-scare-style approach to it and use it as a force of consequentialism against the nation in question having engaged in nuclear assault in order to bring a downpour of shame upon the nation that carried it out.

My problem with it is exactly what yours is, though I don't disagree with doing something about those directly connected to the act.
