Never underestimate these malcontent ideologues.
If Anduin becomes gay, some of them will start whining for a major lesbian character or a non-white human who’s a major character, then a human woman of color who’s a major character after that.
If they want to put these characters in the story in a way that’s organic, they’re welcome to do so. Having female, ethnically diverse or non-straight characters isn’t bad in and of itself. But doing it to appease ideologues is a bad idea because it’s virtue-signaling, usually fake and I’ll sum up the ideologues with a quote of Nuada from Hellboy 2, “Greed has burned a hole in their hearts that can never be filled. They will never have enough!”
