Autistic DM (he/him)
I also second this. I like a lot of media (D&D, Rick Riordan, Brandon Mull, Brandon Sanderson, etc), but I criticize all of it. Because, well, it isn't perfect, and none of it will ever be. However, criticizing the flaws in it can make the writers (and others that read the works) aware to these issues and avoid them in the future, can help avoid absorbing certain harmful tropes, and makes the broader genre better.And also, like… It’s entirely possible to recognize and be critical of problematic elements of something while still enjoying the thing. I do that with… Well, basically everything I like?
Constructive criticism is a good thing. It's not a personal attack, it's just the mere recognition of certain flaws in a piece of writing and helping others avoid and recognize those flaws.
