Callie Crossley, host of WGBH’s Under The Radar, stopped by the WGBH Studio at the Boston Public Library Friday to discuss comments made by Barack Obama at this year’s Obama Foundation Summit.

In his speech the former president pointed some criticism at young people who, he argued, might be too quick to pass judgment on others.

"There is this sense sometimes of … the way of me making change is to be as judgmental as possible of other people,” Obama said. “That’s not activism.”

Crossley said she understood the point the former president was making, but added that, in her view, certain circumstances warrant “canceling," a term used to describe a public fall from grace.

“Listen, I believe in canceling,” Crowley said. "I’m a big canceler – but I think that you need to use it judiciously.”

“For me, I try to see a pattern of behavior,” she said, arguing that continued instances of ignorant behavior warrant a public ousting. "Don’t try to tell me, ‘It was a slip of the lip, it was not in my heart.’ No," she said. "I don’t wanna hear that. Canceled."
