Dumb question from a modern writer

From something called waorsu.org:

“Is it acceptable for writers to incorporate aspects of cultures outside of their own into their writing? Where is the dividing line between a respectful use of other cultures and cultural appropriation?”

Who is to define “respectful use?” By that thinking, I cannot write about any character who is not male, white, a Baby Boomer, born and raised in Texas.

Here’s the thing: Anyone who writes, creates.

Here's another thing: Anyone who asks a question concerning "cultural appropriation" has no business claiming to be a writer.
