ABC reporter shreds Milo Yiannopoulos: 'You're an idiot ... What grade are you in?'

ABC News reporter Terry Moran did not buy into Milo Yiannopoulos' self-portrayal as a "virtuous troll" in an interview slated to be aired Friday on Nightline, Queerty reported.

"If Leslie Jones were right here, would you say, 'You look like a dude'?" Moran asked.

"Yeah, probably," said Breitbart.com's tech editor, who was banned from Twitter after leading a harassment campaign against the comedian.

"You would say that to her," Moran said.

"I probably would," Yiannopoulos insisted.

"Then you're an idiot," Moran replied.

Yiannopoulos argued to Moran that he found the wave of racist and misogynist abuse hurled at Jones in support of him "disgusting," but rejected the idea of telling his thousands of Twitter followers at the time to back off.

"Does Justin Bieber have an obligation to his fans?" he asked Moran. "I'm sorry for being popular. But I am not responsible for what 350,000 people on the Internet say. I'm responsible for what I say."

Later in the interview, Moran berates Yiannopoulos for his sexist stances.

"You're going to go after somebody’s body to denigrate their ideas? What grade are you in?" he asked. "Are you a 13-year-old boy? Because somebody doesn't have a weight that you think is proper? That's revolting."

"I'll tell you what's revolting," Yiannopoulos responded. "What's revolting is the body positivity movement. What's revolting is this idea now that you can tell women that they'll be healthy at any size."
