People who protested the arrest of a writer or poet, or who wanted to try to get the Soviet government to live up to the tenets of the Helsinki Accords on Human Rights were rounded up, diagnosed with "sluggish schizophrenia" and shipped off to a mental hospital without trial.
I read a great book when I was in school, written by a guy named Vladimir Bukovsky, who'd been subjected to that treatment for about a decade in the 1960s and early '70s. After he was deported from the USSR in the late 1970s he wrote To Build a Castle about his experiences in the psychiatric gulag. It's an amazing story.
Anyway, you're probably wondering what the hell brought this up. Well, I just went through the news on my computer and read a few stories that shook this little memory out of the fog and dropped it back in my lap.
Seems that some silly asshat scientist has decided that all of those folks who doubt the connection between Global Warming, climate change and humans are suffering from a "sociological disorder".
