Donald Trump confronted a protester at his event in Radford, Virginia, on Monday, asking the person, "Are you from Mexico?" before security escorted the person out.
That comment was mild compared to what Trump did last week during a rally in Las Vegas, when he said he'd like to "punch" a protester in the face.
"In the old days," Trump added, protesters would be "carried out on stretchers."
And in November, when a well-known black activist in Birmingham, Alabama, interrupted a Trump event, the GOP presidential front-runner told security to "get him the hell out of here."
He later said in an interview that the man was "so obnoxious and so loud" that "maybe he should have been roughed up."
This confrontational approach is standard at Trump events, and it's spread to his supporters.
At a January rally in Lowell, Massachusetts, Trump supporters ripped up protesters' signs and threatened to hurt them.
This approach couldn't be more different from how Vice President Joe Biden handled a particularly terrible protester Saturday night. Biden was giving the keynote address at the California Democrats State Convention when a man started yelling about a particularly delicate topic: Biden's son, Beau, who died from brain cancer in May.
The protester claimed that Beau died due to cell phone radiation. The crowd booed him.
The vice president, in contrast to Trump, tried to calm down the crowd.
"It's OK, it's all right," he said. "It's OK, it's OK. My son Beau would love that part."
"Let's not act like Republicans," Biden added.
Editor's Note: Donald Trump is a serial liar, rampant xenophobe, racist, misogynist, birther and bully who has repeatedly pledged to ban all Muslims -- 1.6 billion members of an entire religion -- from entering the U.S.
