J.K. Rowling slams Donald Trump with Voldemort diss

J.K. Rowling took on Donald Trump with her latest tweet heard 'round the world.

After the Republican presidential candidate frontrunner said that all Muslims should be banned from entering America, Harry Potter fans began comparing Trump to Lorde Voldemort, a.k.a. he who must not be named, a.k.a. the most draconian, dastardly villain in all of literature — well at least in Harry Potter's wizarding world.

But Rowling didn't agree with the comparison. "How horrible," Rowling wrote. "Voldemort was nowhere near as bad."

On Monday, Trump called for the "total and complete shutdown of Muslims entering the United States."

"Without looking at the various polling data, it is obvious to anybody the hatred is beyond comprehension," Trump said. His remarks were slammed by both Republicans and Democrats alike. "Donald Trump is unhinged," Republican presidential hopeful Jeb Bush wrote on Twitter. "His ‘policy' proposals are not serious." <iframe height="390" width="100%" scrolling="no" frameborder="0" src="//renderer.qmerce.com/interaction/566701f2b8db3ddc5ef4c67c" class="" allowfullscreen="" resize="0" replace_attributes="1" name=""></iframe>
