I think your logic is backwards. The main reason for a culture to ban pedophilia is because it causes trauma in children. For thousands of years, cultures have progressed towards protecting children. This came from a natural sense of outrage in a majority of people, which became part of the culture. Not vice versa. In many of your comments, you seem to assume that people are only automatons who think and do exactly what their culture teaches them, but that's not the truth. The culture is made up of individuals, and individual conscience frequently - thankfully - overrides cultural diktat. Otherwise no dictatorship would ever fall, no group of people would ever be freed, and no wicked practices would ever be stamped out. It has always been individual people acting against the culture whose outrage has caused the culture to change. Which strongly implies that people's sense of outrage is at least partly intrinsic to human nature, totally apart from cultural practices of the time.
I'm now old enough to have seen people who treated homosexuals in the 1980s the same we treat pedophiles today start waving rainbow flags and calling the people they beat up for being gay in highschool Nazis.
There maybe a few people with principles who stick with them.
The majority will happily shove who ever they are told to in a gas chamber.
I'm not saying there aren't a lot of people who are natural conformists, who do whatever they're told to, and hate or love whatever the prevailing culture hates or loves. They may be a majority. And yes, a prevailing culture can take even the revulsion of murder out of people to some extent (although check out the state sanctioned degree of alcohol and drug use among SS officers and you'll see it's not quite so easy to make people do acts of murder and torture every day).
What I am saying is that the conformists don't drive the culture, they're just a blunt weapon of whoever is driving the culture. That weapon can be turned toward gay rights or toward burning people at the stake, but what changes a culture are the individuals with either a conscience or the individuals with wicked plans. Both of which exist outside the mainstream in any time and place.
Maybe another way of saying this is that I think most people are capable of murder and most people are capable of empathy (and therefore trauma) with someone being tortured, but primarily they're concerned with being a good guy. What throws the arc of history towards a higher morality is that maybe >0% of people naturally need to perceive themselves as "good" by defending life and the dignity and humanity of other people, to the extent that needing to be a good person overrides their cultural programming. And those are not the only people who change a culture, but 51% of the time they change it for the better instead of worse.
Wait, why are they calling gay people Nazis? This story is very unclear. And I can't see how it relates to CSAM and the moderators who have to see it, which is a categorically different issue to homosexuality, so different as to be completely unconflatable.
