Last week, we reported on the newest initiative by Towson University provocateur and white-pride advocate Matthew Heimbach:  a white student union. As predicted, the outcry has begun; a Facebook-circulated petition calling for Towson’s new president to officially denounce the group already has more than 1,500 signatures. “Allowing a ‘whites only’ student group directly contradicts your commitment to diversity — and it serves no purpose other than to discriminate against non-white students,” the petition says.
