"This artist must be white."

"No SA victim would ever handle the subject in this way."

"No woman would ever write women like this."

"This creator is obviously neurotypical. Everyone with autism/ADHD/depression understands-"

Nope.

People who make these blanket statements are very frequently proven wrong when the creator comes out as a member of that group. And even when they aren't proven wrong, even in cases where the creator isn't from the group in question, actual members of the group who don't fit whatever arbitrary criteria are being expressed will see these statements and feel excluded and erased.

Not everyone in your group is going to share your experiences. No single individual gets to personally decide what does or doesn't count as a "valid" expression of trauma or being part of a particular group, and creators are also not obligated to out themselves in order to "prove" their validity.
