Actor Mark Hamill, who is best known for his role of Luke Skywalker in the Star Wars film series, has upset liberals by merely “liking,” or favoriting, a tweet from the popular Harry Potter author J.K. Rowling.

Rowling is well known for triggering radical leftists with her views on transgenderism.

YES 👍 or NO 👎

A transgender newsreader for Good Morning Britain named India Willoughby initially said, “I’m more of a woman than JK Rowling will ever be.”

Rowling responded jokingly, “citation needed,” in reference to the fact that Rowling is a biological woman as opposed to biological male who choose to identify as a woman.

Hamill “liked” Rowling’s response. Liberals responded by calling Hamill a “bigot.”

It’s unclear if Hamill is agreeing with Rowling because she’s a friend. He is known as a very outspoken leftist and Trump critic.
