Conservative filmmaker Dinesh D'Souza ruffled some feathers during a Thursday appearance on MSNBC, engaging in a debate with the show's liberal host and panel over his new movie "America."

"Ed Show" guest host Michael Eric Dyson asked D'Souza how he reconciled slavery while challenging the "theft and pillage narrative of America's history."

"Well, first of all, you have to remember, the ethic of conquest, the idea that you get land by grabbing it from someone else has been occurring since the dawn of mankind," the conservative filmmaker answered, noting that native Americans often took land from others.

"Slavery was a universal institution, but only one nation, America, fought a war to end it," he added.

Panelists Zerlina Maxwell and Eric Boehlert then asserted President Barack Obama and Hillary Clinton are "very centrist" Democrats, challenging D'Souza's depiction of Obama as a "radical."

D'Souza countered, saying both the president and Clinton have been influenced by Saul Alinksy and insisting such criticism is perfectly legitimate.
