On Rainbow Diversity, Short Fiction Submissions, and Failing To Be A DFW Litbro

Hello friends. I got a good review in Publisher's Weekly for my latest YA. The key sentences are:

Kanakia’s exploration of the spaces between social and medical transition is heartfelt and necessary, and Tara’s complex and realistically contradictory emotions around her experiences are effectively conveyed. Supporting characters read as white.¹

While this is a good review, I want to complain about it, because that is my god-given right as an American. Specifically, I want to complain about the last sentence.
