Educate me please. I know why almost everything is on the list, except for Mad Max and EarthWorm Jim, so what did their creators do?

Harry Potter: JK Rowling is a TERF, "trans exclusionary radical feminist." She's the kind of radical feminist who is bigoted towards trans people, seeing transwomen (male-to-female) as "men who are trying to invade women's spaces" and viewing transmen (female-to-male) as "gender traitors."

Dragon Quest: Not the creator of the series (Yuji Horii), but its long running composer (Koichi Sugiyama) has been on TV programs where he spoke against equal rights for LGBTQ+ people in Japan. He's also a man who denies Japan's old war crimes like the Nanjing Massacre.

Minecraft: Notch has indicated he legit believes in the Q-Anon conspiracy nonsense, and has said some questionable things about trans people in the past.

Rurouni Kenshin: Creator Nobuhiro Watsuki got caught owning pornographic DVDs depicting teenage girls under 18.
