Misleading headline: if you read the article and watch the video, he actually blames school shootings on the lack of moral education, with merely a reference to evolution teaching as an example of amoral atheism in the classroom.
So it’s not a cartoonish slogan, it’s actually a fairly standard fascist talking point.
And people say, ‘How can a young person go into their schoolhouse and open fire on their classmates?’ Because we’ve taught a whole generation, a couple generations now of Americans, that there’s no right or wrong, that it’s about survival of the fittest, and you evolve from the primordial slime. Why is that life of any sacred value? Because there’s nobody sacred to whom it’s owed. None of this should surprise us.
