I'm realizing I have issues with diversity in my story. I have three main characters and all of them are white men. Now, I'm not racist. I have all sorts of races in my story as it takes place in a future America, so it's naturally diverse. I'm also realizing a shortage of women. I have women side characters and stuff, but only one or two play somewhat important roles and that. This may all be due to the characters themselves, one of them is very arrogant and ignorant. I refer to some soldiers sometimes as "her" or "she", equally with "he" and "him". But I'm feeling like some people are going to take this to heart and take me for a bad guy. Is this a valid concern I should have? I don't want to change my characters because they're just the way I want them, but I'm worried that the lack of diversity, at least in main characters, is going to be an issue.
