The "Politically Correct," silence on the subject must end. Trump has already wounded the self-destructive & stifling mentality that is behind it. But we have to expose it as the lunacy that it is.

In the same way that there is no point in a wall with no-one to man it; what is the point of the largest and most technologically advanced military on the planet if the society that it represents and defends will never agree to use it? The progressives have been rotting the moral and cultural underpinnings of American society (and Western society generally) for decades. A frighteningly large proportion of US college graduates have been taught to despise and disparage their own country and culture almost reflexively. And most of the rest have been cowed into silence.
