This feels rather… “ironic” definitely isn’t the right word here, but not sure what else to use… in contrast to a work of fiction that I read very recently. Rampant sensuality, kink, sex, and drug use, in a similar vein to Brave New World and similar “utopian dystopias”, but forced on humanity by questionably “benevolent” aliens. The contrast here is that rather than this being “enforced narcissism” the aliens are creating an environment of ego death and near-pathological selflessness (and also learned helplessness, in some cases), which is the exact opposite. Meanwhile the people branded as “narcissist” and/or “psycho-spiritually unhealthy” (to use the OP’s words, not the in-setting terms) are the religious fundies, fascists, violent criminals, and greedy hyper-capitalists. Those people “need” to be trained out of their dangerous mindsets, or failing that (and it doesn’t take much to fail), get non-consensually blissed out and memory-wiped to the point of near-total personality death and made a personal ward of one of the aliens - “for their own good”, of course.
Neither view is inherently right, though. There is indeed such a thing as a “psychologically healthy sex pervert” (I’m not going to include “spiritual” into that because what “spiritual” means and how it’s experienced varies considerably between individuals, and for some people it’s a meaningless concept). But also some “sex perverts” very much aren’t, or become unhealthy because they’re approaching it in a very wrong way. This is further confounded by the fact that what is truly “selfless” and “selfish” is both context-dependent and mindset-dependent, and things can be both at the same time, which is why some people throw the narc-word around a little too casually in social, political, and religious discussions (due to ignorance and/or misaimed empathy). It’s a complicated subject, but I don’t need to watch a $20 video on “Diabolical Narcissism” to know that whatever the OP’s full views are, they’re utter trash.
[Edited for clarity] [Addenum: when I read it I wasn’t interpreting “sex pervert” as “gay”, just more generally]
