This may be contrary to cultural signaling, but the person you are in any given moment is determined by your behavior, not by the special adjectives you apply to yourself.
In other words, stop focusing on communicating that you are an asexual 1/26th Native American, autistic, ovo-pescatarian, and start focusing on having manners and treating other people with kindness.
It hurts to let go of your special status, but being able to engage with other people as an actual human being (instead of a description) will massively improve your experience in this world.
