Not the shooting part but this has been part of the leftist agenda for a long while, here in America. Take control of the schools and you control the future of America. All it takes is getting the right people in the hiring positions and then it is all over. Ask Soros why he is interfering with the SoS positions all over the USA. Same rationale.
Not just the schools, the sciences (healthcare by which I mean CDC, NASA, and others), the media and entertainment and history.
A cultural revolution is going on, burying the past. Michelle Obama herself said that history was going to have to change.
Mao and the muslims DESTROY evidence of the past, Hollywood and the SJWs do that too.
