You mean where do these children get these idea?
If this went on when I was in Junior and Senior high school we certainly did not hear about it. I’m sure there was some sort of hazing but never like this, at least we hope.
Yes — children. Sometimes I read of even younger children committing acts of a violent sexual nature. It shouldn’t even cross their minds at that age to do that. I assume it comes from exposure to pornography, which you can find online without even looking for it, or they are being mentored by someone older.
