That shooting, is the untimate evolution of the victim mentality.
When hours and hours every day are spent...telling...teaching...indoctrinating...that nothing is ever your fault, and that every problem and burden and hurdle that you face in life is someone elses fault...day in, day out...year in, year out...
Sooner or later someone is going to believe it, and maybe even take it seriously.
The DUmmies used to talk a lot about stochastic terrorism.
Now, they both practice and support it.
