I will also confess to ignorance. I had never heard of The Eye of Argon, but I did have the common sense to Google it before posting this message. It has a 47% rating on Goodreads, so it cannot be that bad.
I just read the first page of The Eye of Argon. The prose is very purple, but that's sometimes fun. I see only one very minor grammar issue, so at least it got a good proofreader. I have definitely read worse. Heck, I've read worse on Tapas.
Maybe the issue with Eye of Argon was that the style passed out of favor, so a very vocal minority hates it (maybe). The author has no control over that.
The even bigger but related issue is the trend of contemporary readers going out of their way to the works of guys like Lovecraft, Henilein, and Card because they don't like the author or social or political reasons. To a degree, an author can control this by being the objectively best person possible, but even that stretches only so far into the future. Any person who thinks that he or she will not be vilified by future generations by their standards of morality is fooling oneself. I think I'll be in my sixties by the time younger people are spitting on me in the streets and telling me that I should be in prison.
To answer the question, Diego already gave better advice than me. I would add...
- Don't be a jackhole.
- Do not misrepresent your story's content by its genre label or description.
- Read diverse authors yourself so you don't become an inferior imitation of the only author you do read.
