The first step is listening to concerns. Not dismissing them. Or insisting nothing is wrong. Okay to disagree.
Massive problem in society is tribalism. Goddamn need to change this
Changes to Vistani are a start. Good start. Changes to orcs are a start. A good start. And changes to other non humans will be a start. More good starts. Of course you are free to do whatever you want.
If there are problems with depictions. Then Wizards should find other ways to depict them. The problem is other people upset at changes after the fact.
You have a whole of slew of purely fictional evil in the monster manuals.
Then more research is needed. Even for a roleplaying game. No one said it would be easy. But it is a step Wizards is taking.
The Vistani of CoS and Ravnos WoD are offensively racist in their portrayal. Which is why there are changes made to the Vistani. And a massive backlash to the Ravnos. Yet you and Mercurius find no problem with this.
Frost giants are a problem because of one dimensional Nordic caricature. Likewise a problem in other one dimensional cultural caricatures. Are a goddamn problem.
Purely fictional evil is fine.
Actually listening. Instead of continually ignoring. Or making excuses. Would be a good start. Then that is something you can actually work on. Otherwise. Yeah.
