The logical outcome

To bury the modern concern for victims under millions and millions of corpses——there you have the National Socialist way of being Nietzschean. But some will say, “This interpretation would have horrified poor Nietzsche.” Probably, yes. Nietzsche shared with many intellectuals of his time and our own a passion for irresponsible rhetoric in the attempt to get one up on opponents. But philosophers, for their misfortune, are not the only people in the world. Genuinely mad and frantic people are all around them and do them the worst turn of all: they take them at their word.—Girard, I See Satan Fall Like Lightening, 175

Everything in that paragraph could be said of today's politicians, couldn't it? And of many media personalities. Or, as a book I read as an undergraduate for a philosophy class put it: Ideas Have Consequences. C.S. Lewis also touches on it in That Hideous Strength (he has a way of saying stuff in fiction that many can't express in essays).

One of my professors in seminary used to say that the ramifications of your ideas will be seen in your students. And he was correct, which can be a scary thought.
