If someone doesn't understand what you mean, you didn't do your job as a writer. That understanding must be on the page. If something is unclear to the writer, ask the person who made the remark. Take the question to private email. Keep an open mind.
Readers have likes and dislikes.
Some of the best comments can come from someone who doesn't generally read that particular type of story. They may be able to see more clearly problems because they are not trying to overcome their own natural bias for or against the subject material. Readers of commercial fiction will accept anything that strains the practical boundaries of their lives, as long as the believable is made believable. Believe in your work. Make every word count.
