Especially when it comes to sticking up for people against bullies.
While J.K. Rowling has blasted president Donald Trump on multiple occasions, it didn't stop her from going after him again in the most Harry Potter way ever.
She shared a photo of somebody dressed up as Donald, with the caption, "Warning: there is a Boggart on the loose in Times Square."
For those of you who don't know (how dare you), a Boggart is a shape-shifting being that turns into your biggest fear in life. Pottermore describes it as "The more generally fearful a person is, the more susceptible they will be to Boggarts.... Like a poltergeist, a Boggart is not and never has been truly alive. It is one of the strange non-beings that populate the magical world, for which there is no equivalent in the Muggle realm."
Naturally, HP fans were quick to jump in. "Are we sure it's not a Dementor?" one person asked. "I feel cold, like all the happiness in the world has been sucked out of me when its is near."
