Defining What's Threatening

Amazing what's happening at Brown University. The university has revoked a speaking invitation to Nonie Darwish, author of "Now They Call Me Infidel: Why I Renounced Jihad for America, Israel, and the War on Terror." What's the problem -- that her message will "offend" the proponents of jihad?

Note that Brown's sensitive concern doesn't extend to evangelical Christians. The student evangelical Christan group has been banned from advertising or meeting on campus.

Doesn't look like the university is any friend to the first amendment -- whether it has to do with religion or speech -- does it?
