That's bad enough but what's worse is that the lecture didn't raise any eyebrows at the university where he professes to know stuff nor elsewhere, except for several blogs that can be seen here and here.
Even Jihad Watch picked up the story and is an excellent website to learn more about Islam from the expert, Robert Spencer (not to be confused with Richard Spencer).
Brown, a 39-year-old convert to Islam, actually said that "It's not immoral for one human to own another human."
He speaks glowingly of the wonderful life a slave has under sharia law, as opposed to slavery under white men in the U.S. South, but doesn't actually describe that life. He should probably ask a sex slave, say for instance a Yazidi girl from Iraq, what it's like to be owned by a Muslim man against her will. What it's like to have to endure being raped at his whim.
But Brown claims slavery itself isn't problematic because "the Prophet of God [Mohammad] had slaves . . . There's no denying that. Was he--are you more morally mature than the Prophet of God? No you're not."
Yes, we are, "professor." We aren't living in the Seventh Century and we find the notion of sex slaves as repugnant as the notion of the Qur'an sura that says "Kill them whenever you find them." As repugnant as beheadings in the name of Allah and your prophet.
Brown claims that "There is no such thing as slavery, as a category, as a conceptual category that exists throughout space and time trans-historically." Then he adds another pile of warm dog crap: "Slavery cannot just be treated as a moral evil in and of itself because slavery doesn't mean anything."
Insofar as sex with slaves is concerned, he says: "Consent isn't necessary for lawful sex." And that would be true under his law of sharia. But we don't live under his law--he lives under ours--and a man can't take what he wants from a woman against her will. However, he disagrees and says that our society is "obsessed with the idea of autonomy and consent."
I could go on about this asshat's thinking but he's not that interesting and certainly not that erudite. I suggest you read the blogs (linked above) and form your own conclusions about what has gone wrong with our schools in the West.
