Althouse: When did the left turn against free speech?: "Remember when lefties were all about free speech? When did that change? Why did that change? Perhaps the answer is: Free speech was only ever a means to an end. When they got their free speech, made their arguments, and failed to win over the American people, and when in fact the speech from their opponents seemed too successful, they switched to the repression of speech, because the end was never freedom."
