Hillary Clinton repeatedly insults Heckler at the Bonkers Exchange

Hillary Clinton tried to silence a histrionic heckler this week in a tense exchange that lasted several minutes. (Watch the videos below.)
When Clinton appeared on a panel discussion for the Institute for Global Politics at Columbia University on Monday, she was harassed by the protester about half an hour into the event.
The man, identified as Robert Castle from the Schiller Institute think tank began harassing Clinton over her support for the “warmongering” president Joe Biden while playing to the crowd as he stood up.
The persistent protester said Biden’s $100 billion aid proposal to help Israel, Palestinians in Gaza and Ukraine was a push into World War III.
“I’m sorry,” he said of his interruption.
“Well, I’m not sorry. Sit down,” the former secretary of state and first lady shot back.
“I know you’re not sorry. That’s what it’s about,” he replied, repeating the request for comments about Biden current speech in prime time to solicit funding.
“You can’t have a conversation like that,” she said. She invited the man to talk to her afterwards. “I don’t believe you,” he replied.
Undaunted, the man shouted, “The voices of the American people must be heard.”
“That’s my opinion,” he said.
“Well then sit down. We heard your opinion, thank you very much,” Clinton snapped.
The man said he was exercising his freedom of expression. “It’s not free speech if you disrupt everyone else’s ability to speak,” she clapped back.
In a shaky voice, he discussed Eleanor Roosevelt and John Foster Dulles, taxing Clinton’s patience. She then tried to introduce Ugandan activist Frank Mugisha, “who is actually on the front lines fighting for human rights, not just shouting about it.”
Castle kept his volume up and said the stakes weren’t like a football game or Team America.
“I’m sorry, but some of us are on Team America despite our flaws,” Clinton said to applause.
Finally, Historian and Clinton advisor Allida Black had had enough and said to Castle, “What have you done but stand up and disturb?”
