I know it can be tough, feeling like you're giving mspec and polyam folk a bad name for 'falling into stereotypes' due to your aromanticism. You're not at fault for those stereotypes existing, nor do you hurt anyone by existing as you do; you're simply living as your authentic self, and that's to be celebrated! You're a valuable part of both communities, your unique perspective and experiences is a good thing, and if you haven't found peace with yourself and your identity yet, I hope you do soon.
