Young white males are also relentlessly inculcated with the idea that they have utterly no future in America. Everything wrong with America is their fault. Everything they have is as a result of privilege. And what is certain is that society is now bound and determined to right that injustice by revoking their future, socially exiling them, and taking away any hope they might have had for a prosperous future. They are first to be blamed for all societal woes and what’s even more insidious, they have no way to right this wrong. Through no fault of their own, illegals are to be given every right and absolved from all but the most heinous of crimes. Through no fault of his own, his very skin color is in itself a badge of dishonor and a guarantee of a demeaned future. It’s not hard to imagine if you put yourself in his shoes that you are doomed to a seriously diminished future, and while it is of course insanely wrong and inherently evil to take this out upon society by conducting a wanton slaughter, if we’re talking about causes, this is a definite something.
