The view is relatively extreme because of constructed social norms, but when I was 14, I had the same view, and it was shared among the peers that I associated with. It would be hypocritical for me to say the points you quoted are abnormal, because in my experience, that's what being 14 was like.

Consensual encounters between underage high school freshman and adult high school seniors are certainly different than a DHS employee, but which one is more "moral" depends on the framework you use to evaluate trust. For example, atleast DHS employees get background checks. And which of those two groups are better known for carrying out school shootings?

My points are: Stallman's relatively extreme views are not absolutely extreme views; and overall, the amount of gray area in the subject makes it complicated.
