Look at what's happened to Larry Summers, a highly qualified member of the liberal establishment and Clinton's former Secretary of the Treasury. In an academic setting and at a meeting called to discuss why there are relatively few women at the higher levels of hard science, he speculates, on a substantial academic basis, that it might be due to innate differences between men and women. He's immediately subjected to a hysterical, screeching Maoist denunciation and forced to undergo humiliating self-criticism, just as he would have been in Communist China. "Academic freedom" is for the Marxists as long as they sprout Marxism, nobody else.
