A long-time 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."
He also opined on gays in the aftermath of the Supreme Court decision to legalize same-sex marriage nationwide: "The servants of Allah, will oppose Obama's homo uprising..."
Siddique was off campus for the summer and did not return an email for comment on his remarks, many of which were first reported in The Daily Beast.
Lincoln, a historically black university in Chester County, said Wednesday that it planned no action against Siddique, though it condemned his remarks and noted that they do not represent the views of the university.
As a "state-related" university in the same class as Temple, Penn State and the University of Pittsburgh, Lincoln receives some state funding, but is not part of the Pennsylvania system of higher education.
"His latest activities, like his earlier writings, statements and activities, are an insult to women and other groups singled out," the university said in a statement. "Like all faculty members, he is entitled to express his personal views in conversation or in public forums, as long as he does not present such opinions as the views of the university."
Less than a year ago, Lincoln became embroiled in controversy over remarks made by its president at an all-women's convocation on campus. Robert R. Jennings resigned in November after his statements that some critics interpreted as blaming women for sexual assault.
Siddique has taught at Lincoln since 1985 and holds tenure. He told the Inquirer in 2010 that he was against Israel - not Jews - and that he would not be cowed by detractors trying to "threaten academic freedom."
In an interview with The Daily Beast, the professor also defended his more recent Facebook posts, which he said he made as a private citizen.
He said the comments he made about "sluts" were taken "a little out of context." He posed five explanations for why it took so long for women to accuse Cosby of sexual assault.
"I was asking my readers what they thought of these five possibilities," he told the Daily Beast. "The reason I was writing five items is because I'm not sure what is going on with American women."
The other reasons, he mused: "He paid them off." "American women are slaves of rich men." "Random sex is quite acceptable in America." "They don't have families like Muslims do who would take revenge for rape."
Siddique, a Muslim original from Pakistan, also told the online publication he's not homophobic and that some of his best students in class have been gay. But those who oppose gay marriage, he said, have become the "new persecuted minority."
Charles Pettaway, chair of visual and performing arts at Lincoln, said he knows Siddique well and his colleague has never shared those sorts of views with him.
"His persona at Lincoln is probably different from his persona somewhere else, and I don't know the persona from somewhere else," said Pettaway, who has taught at Lincoln since 1987.
Of the most recent posts, Pettaway said: "If in fact that's true, and I hope it's not, it's a shame.. . .I don't support that."
