IMO, the article is quite right in pointing out that things like drug use, free love, homosexuality, etc. have been maliciously promoted by the Left. 'Course this was not done by them through any love of hedonism or individual freedoms, but in an effort to damage the basic building block of our civilization, the American family.
Those things are in no way truly leftist values, though, they are only being used by the Left as tools. The main suckers are those who call themselves liberals. They would not likely be tolerated very long in a completely socialist society, which would be totalitarian by nature.
However, I'd like to respectfully point out that such basic things as the freedom of choice and the right to privacy from government intrusion, which were disparaged by the author, are intrinsic not only to libertarian philosophy, but to the American ideal of freedom.
The words "choice" and "privacy" are used by liberals/leftists as code words that really mean something else to them.
"Choice" means "killing unborn babies" and "privacy" means "promotion of sodomy" or even "sodomy on the street/in the park/at the beach/in the public toilet".
Real choice and privacy - within legal and philosophical limits as delineated in the Constitution - is vital. But leftists don't mean real choice or real privacy. They're just codewords to them.
