It appears that Luke Skywalker wants you to fear the Joker. Mark Hamill, best known for his “Star Wars” role, took to Twitter this Independence Day weekend to mock pro-lifers who are willing to adopt the babies of women who choose adoption over abortion. He used a picture of the Joker, a villain whose voice Hamill provides in a television cartoon, to add to the overwrought climate of fear in the wake of the Supreme Court’s overturning Roe v. Wade. (For what it’s worth, the fictional Luke Skywalker and his sister, Leia, were both adopted.)
