A longtime Lincoln University professor drew ire from Pennsylvania officials in 2010 when he called for the destruction of Israel and questioned whether the Holocaust ever happened. But Kaukab Siddique, a 72-year-old associate professor of English, kept his job. Now he's mouthing off again. "Don't be scared of these dirty Jewish Zionist White Supremacist thugs," he wrote in a Facebook post in May. Earlier this month he wondered why it took Bill Cosby's accusers so long to come forward. Is it because "many women are sluts"?
