Jacksonville Madden Tournament Shooting - "Rethink your life" Says Bob Chipman

"This game has no guns or sexism depicted in it, so clearly the problem is guns and sexism"

That is circular logic: there are male shooters because of toxic masculinity, and there is toxic masculinity due to male shooters.

Nor is the shooter in question a good case study of toxic masculinity since he was mentally ill and was prescribed anti-psychotics which, either, did not work or he did not take.
