Don't you worry about high IQ humanistic dudes losing their innocence in the face of suffering around the world. They know how to open that damn computer, they know how to get ahead socially.
To develop relational capacity, requires relationships. To maintain any functional relationship, not even a very happy one, requires self-criticism. Maybe that's why most people don't try to be writers as it turns out the majority of everyday issues don't have clear answers and it's a slippery slope mistaking self-righteousness for being insightful.
People engaging in splitting are able to convince a large group of people because they offer immediate answers. And when our needs day to day life are constant, when anyone offers a shortcut, it's very convenient not to question it. I guess we are all in that position from time to time. The worse off financially or emotionally, the more we are vulnerable to it.
Part of why it's so convincing is the splitters do believe in what they sell. We are talking about people who see no hate or aggression in themselves. Just that they think the culture war is pointless because it's too domestic to be manly, doesn't mean they don't carry the splitting techniques elsewhere. Now that it's for the future of humanity, it's socially acceptable, and especially socially profitable as a boy/man/whatever to tell people what to do as moral obligations.
Of course, splitters never understand why it's narcissism 101 (moral sadomasochism to be specific) because their relational capacity stops at a 3 year-old to spell out this observation “I'm so sad with all the fighting. They are like brothers and therefore shouldn't do that”. And all other humanistic dudes applaud for this empathetic statement because they are splitters too and that familiar outfit looks authentic to them.
