Might be a good time to step away and take a breather for a bit. I say this because your sentence structure is no longer really making sense to me and that tells me you're typing emotionally rather than considering your words carefully. Do something you enjoy for awhile and get your mind off of this facebook argument and then go back into doing what you want to do.

You're never going to find people agreeing with you 100% of the time, and when you're dealing with issues such as race you're bound to find yourself on the receiving end of sharp criticism and critique especially when you don't identify with those groups. When it comes to your own writing, your authorship is your own and consider the successes of other fiction authors and how they've handled race in their works if you want to avoid drawing comparisons to contemporary race issues.
