It has nothing to do with puritanism.

It's schools covering their asses for fear of harassment lawsuits.

This is the same reason that they've taken the swings off the playgrounds at many schools, and monkey bars, and a lot of other gym equipment that was normal in my era: Parents have sued.

So, it has everything to do with the litigiousness of American society and nothing to do with uptight pilgrims.
