Once more, it appears, Fredric Wertham may have been right.
For the latest evidence, look no further than a Philadelphia preschool, which has purportedly banned "wrestling, Super Hero play, and Monster games," because they're resulting in injury.
Reddit user Oremar posted a May 17 letter (below) brought home by his son that states, "Recently it has come to our attention that the imaginations of our preschool children are becoming dangerously overactive causing injuries within our pre-k community. Although we encourage creative thinking and imaginary play, we do not promote out [sic] children hurting one another. Wrestling, Super Hero play, and Monster games will not be permitted here at [name redacted]. In addition, please monitor the different media that your children may view. The re-enactment of televisions [sic] shows/movies are being done during active paly [sic] times in school."
Or, in the words of the parent, "So my son came home and told me make-believe was not allowed at school anymore."
When ROBOT 6 contacted the preschool this afternoon, an employee said she was unable to verify the letter, referring us instead to the facility's director, who was unavailable.
