What does this have to do with black students weeping during a protest against David Horowitz's views on reparations for slavery?
The impossible situation in which black students have been placed by well-meaning double standards has led to a whole protective make-believe surrounding them, much like the huge plastic bubbles used to surround children born with wholly inadequate immune systems, who must be protected from the slightest risk of infection.
Within their protective bubble, black students are insulated from any criticism of their performances, behavior, or ideas. Draconian speech codes and automatic accusations of "racism" protect them from anyone who says anything to oppose what they say, do, or demand.
What David Horowitz has done is puncture that protective bubble. He has treated black students the way he would treat anyone else. But the facts and logic that he would use in debating anyone else are shocking things to those who have not been used to having to confront them, and are therefore unequipped to cope with them. Their options are to deny or be devastated. Tears and rage are about the only responses available.
Horowitz is not merely threatening their position on a particular issue, but their whole protected world inside the bubble. No wonder they wept. We should all weep that such a world of make-believe was ever created in the first place.
