Michelle Mallkin notes an incident at a Kentucky college, in which a professor brought her graduate class out to destroy a pro-life display of crosses, placed with the permission of the University administration:

Here’s the article she links, plus the salient passage:

Sally Jacobsen, a longtime professor in NKU’s literature and language department, said the display was dismantled by about nine students in one of her graduate-level classes.

"I did, outside of class during the break, invite students to express their freedom-of-speech rights to destroy the display if they wished to," Jacobsen said.

Asked whether she participated in pulling up the crosses, the professor said, "I have no comment."

She said she was infuriated by the display, which she saw as intimidating and a "slap in the face" to women who might be making "the agonizing and very private decision to have an abortion."

Jacobsen said it originally wasn’t clear who had placed the crosses on campus.

She said that could make it appear that NKU endorsed the message.

Pulling up the crosses was similar to citizens taking down Nazi displays on Fountain Square, she said.

"Any violence perpetrated against that silly display was minor compared to how I felt when I saw it. Some of my students felt the same way, just outraged," Jacobsen said.
