Disturbing video shows an interracial couple being harassed by a bigot who calls a Caucasian woman “the lowest rung of humanity.”

The video, posted to World Star Hip Hop on Monday, shows a black man and a white woman sharing a meal at an undisclosed restaurant when the man begins the racially motivated rant.

“Look at this f—–y in a black-owned restaurant,” the man filming says to himself. He then asks the pair if they are a couple.

After the diner says yes, his harasser continues: “You had to go to the lowest rung of humanity? … If they are even humans. Like are you that weak?”

“Just the fact that y’all have the audacity to sit in a black-owned restaurant, you know, I had to ask,” continues the unidentified bigot. “What’s wrong with you?”

“What was it that made you that weak — that you’d get on your knees and bow to this less of a female — that’s lesser than a black woman in every way,” he adds.

But the diner doesn’t lose his cool.

“Luckily for you, I am not getting offended,” the man responds.
