It’d be hard to find a more glaring example of ingratitude; but it’s one of those things you pick up when you shed your Christianity.
The secular worldview being wrong, a secular education can’t help being wrong, too. I was once excoriated by a PBS watcher who claimed to be teaching “critical thinking” to her two-year-old… to keep the child from being hornswoggled by the Bible.
So much nicer to be hornswoggled by a teachers’ union!
