comment: I'm just puzzled at why this is framed as a new thing
  When I was in school decades ago we needed permission slips signed before we could sit in Sex Ed. Permission was also asked for including kids in things like Christmas celebrations, or even in high school you had to have permission for the 'global issues' class that covered things like world religions, the Holocaust, and the Rwanda genocide
  Similarly, school libraries and computer browsing were always monitored for unsavory content
  None of this is new
