Humorous responses to Donald Trump's not-funny remarks from J. K. Rowling and more

Following his recent comments that Muslims must be banned from entering the U.S., presidential hopeful Donald Trump experienced quite a backlash both at home and abroad.

At home, the White House responded to the Republican candidate's remarks by saying that they disqualify him for the office of president, adding that his campaign has had a "dust-bin of history" quality to it.

U.S. Secretary of State John Kerry also lashed out at Trump, saying that his remarks "are not constructive, and that is putting it diplomatically."

The Republican presidential front-runner on Monday called for a ban on Muslims entering the United States in response to a California shooting spree last week by two Muslims who the FBI said were radicalized. 

The Democratic mayor of St. Petersburg, Florida, Rick Kriseman, said in a tongue-in-cheek tweet that he was barring Trump from visiting the city. "I am hereby barring Donald Trump from entering St. Petersburg until we fully understand the dangerous threat posed by all Trumps," Kriseman said. 

Noting the reasons behind his proposed ban on Muslims, Trump said on Tuesdaythat "we have no choice but to do this," and that "we have people that want to blow up our buildings, our cities. We have to figure out what's going on." 

Meanwhile, fellow Republican candidate Carly Fiorina tweeted that "Donald Trump is Hillary Clinton's Christmas gift wrapped under a tree," referring to the effect Trump's remarks could have on the presidential race.

Abroad, British Prime Minister David Cameron "completely disagrees with the comments made by Donald Trump, which are divisive, unhelpful and quite simply wrong," according to his spokesman.

Also in London, Mayor Boris Johnson, who apparently took offense at Trump's remarks that some parts of London "are so radicalized that the police are afraid for their own lives," fired back.

Trump's comments, Johnson said, were "complete and utter nonsense," adding that "the only reason I wouldn't go to some parts of New York is the real risk of meeting Donald Trump."

In France, meanwhile, Prime Minister Manuel Valls tweeted that "Mr. Trump, like others, is stoking hatred and misinformation. Our only enemy is radical Islam."

Not only politicians commented on Trump's remarks. "Harry Potter" author J. K. Rowling also joined the critics, tweeting, "How horrible. Voldermort was nowhere near as bad," referring to the arch villain in her popular book series.
