I don't think they're pedo posts.
The first seems to be investigating a concept that is sort of postmodern, where instead of taking things at face value we have to dig 15 levels in to find hidden meanings. It also seems to be pointing out the fact that the concept has no direct meaning and it's used as a woke weapon.
The others look like they're reasonable posts talking about how we don't treat teenagers as if they're going to be adults soon. I tend to agree, we keep on expanding "adulthood" but really in our 20s we're adults and we should be trying to raise kids with this in mind or they'll make terrible mistakes in their 20s.
