In today’s political climate it is almost impossible to keep politics away from your author brand. I say screw being neutral. Art is supposed to stir the emotions, convey the authors world view. It doesn’t matter if you write non-fiction or fiction, romance or horror; at the end of the day your political and moral beliefs will shine through even the most critical of editing.
My words of advice, don’t hide it. Be true to yourself and your beliefs. At least as much as you are willing to publicly defend. I am not privileged enough to be able to separate politics from my daily life and therefore I don’t stress about even trying. It can be a burden at times but mostly its freeing. You don’t have to like or agree with everything I say but I encourage you not to separate the person from the art.
