We all know and love the author J.K. Rowling for her mega book series Harry Potter. And for the most part she's proven to be a great human being as well, tweeting about things like gender equality in the past.
But recently on twitter she liked something that has caused quite a stir online among her fans.
That's right, J.K. Rowling actually can do something wrong.
So what was it that she liked? And what was so wrong with it?
The tweet, which was written by someone who has now deleted their account, read:
"I was shouted at by men at my first Labour Party meeting aged 18 because I asked them to remove a Page 3 calendar. "I've been told to toughen up, be louder, stronger, independent. I've often not felt supported. "Men in dresses get brocialsit solidarity I never had. That's misogyny!"
In case you're wondering what is wrong here, and why her fans are so upset with her over it, it's because of the "men in dresses" section of the tweet.
Some people are saying that Rowling's action is an example of transphobia.
A spokesperson for Rowling said the writer suffered a "middle-aged moment," when she liked the tweet.
Rowling herself has yet to comment on the matter.
But this is clearly another instance of social media being all knowing. Even something as small as a liked comment can define a person and their intentions.
