This is a simple matter of definitions. The left IS for 'diversity'. It's just that they define it differently. To them it means differences in appearance. They love presenting a photo of faculty made up of every color in the rainbow.
BUT, to them it never means diversity of THOUGHT. That is 'intolerable'. Under the guise of tolerance, the left has systematically created an intolerance, and the thing that boggles the mind is that they're unaware of it. - mscgeek1
