really fun and you're missing out," and show them some CP of kids having fun getting their dick or clit sucked, then it might cause kids to add to their list of grievances that they don't get to do that stuff.
When I was a kid, I thought it was fun to mess around with other kids; I was never punished for it that I recall, and if I had been, maybe I would've internalized that I'd done something "bad," idk.
Most people base their opinions somewhat on the propaganda they've received, or if they don't receive propaganda about a given issue, they don't think about it. Imagine if the media hadn't made a big deal about George Floyd and similar cases; maybe police brutality wouldn't have made it so high on the list of black concerns.
Most of the concerns of kids, like bullying, pointless homework, etc. are issues that are pushed right in their face; stuff is being forced upon them. Or, stuff they see is available, but aren't allowed to have; e.g. "Timmy got a cookie and I didn't." If they hadn't seen the cookie, they wouldn't have thought to want it, or at least it wouldn't have been so high on their list of desires.
If a kid knew that all the other kids were allowed to do something sexual, and heard descriptions of it or saw pictures that made it seem alluring, they might have a problem with being left out. People tend to compare what they have with what others have.
There are probably plenty of teenage girls, btw, who resent that they don't have the same access to older men that older women have; in fact, they often do something about that, by finding an older man to have sex with, regardless of what the law says. And there were boys involved in the founding of NAMBLA, plus that one young British YouTuber years ago who used to create those pro-pedo vids.
