I like authenticity in the writers I read.
I have moral issues with certain demographics writing AT other demographics. But that is a me issue, not a critique of them. I'm a bit of a Vegan when it comes to what I read/watch, I like a certain amount of honesty in it.
That said, when an author crosses the divide and actually writes FOR another demographic, that's when it blows the socks off. I want more of it, I want to be able to enjoy a story that speaks to me in a voice I know rings true.
I think the intentions of the author shows in their writing. And those writers that understand their characters and the motivations, those are the best ones.
