This whole conversation reminds me of when I was sitting in a movie theater, watching Inglorious Basterds-- celebrating the death of an on-screen villain who is in a movie theater, watching a movie celebrating the death of an on-screen villain. Most people never step back and notice the irony of that scene and what it is supposed to say about ME, the viewer. Many people don't realize that they are a continuation of a cycle of villains, both the oppressed for one moment and the oppressor the next, demonizing groups as evil for some sort of tribal emotional reward deep in our ancient brain structures. And to that, I say, it's a very human instinct and though possibly the instinct is the root of most evil in the world, it's not something to hate someone for indulging.

There is but we live in a liberal society, and by definition if they reject it that makes them radicals (though more a "top = totalitarian" kind for both, rather than right or left)

The whole point of the OP article is that a radical leftist view is taking over major social, cultural, and academic institutions.

The author provides plenty of examples for this in the article, some of which are well-known, and none of which are factually disputed.

It seems the ones who ignore reality are those assuming and/or pretending "the center" is still firmly in control on these issues. That simply is not the case, which is really a key point in the article.
