Nice, you are a great writer — your audience is out there, self publishing is clearly your way in.
I’m also shocked to see so few people coming from minorities holding any sort of key roles in the industry. And not only in publishing.
However, I think it doesn’t only apply to minorities, or women, people with disabilities, etc.
I’m sure many white males reading your experience will share that feeling. Perhaps their crush at school didn’t like short boys? or ginger hair…
