Politically correct?

I actually am not even talking about gun control, though I support it. I digress. Whenever they have these films about school murders by teens; It is always by someone that has both parents. The elephant in the room is that overwhelmingly, the people that go on these shooting rampages are raised by single moms or grandparents. Research , which is easy to do, the mass murders and more often than not, it is done by a child without a male role model, not even a bad one, as we had in this film. Society is afraid to even mention this fact.
