Interesting article. I don't know that he makes a very clear point though.
I wish he could have went more into the perversion of liberalism, Amazingly the left has co-opted the word, so much in fact that an American Liberal is only a Liberal in America, everywhere else they would be socialists/social-democrats. And to top it off our public schools rarely, if ever go into the issue, because the very people who co-opted the term, control public education.
