Humans tend to like being addressed with labels like “man”, “woman”, and “person”, rather than “male”, “female”, and “critter”. They tend to dislike having it/its pronouns used to refer to them. While some of them like being pet on the head and given treats, it’s less than many animal species. Since you’re a dragon furry, a critter might assume you identify as a dragon and start talking about the wings, tail, horns, and claws they imagine you to have. I’ve even seen the assumed presence of horns cause body dysmorphia in the dragonkin community, between dragons who have horns and dragons who don’t.
And I’m actually treating you as a human right not by treating you like you don’t already know all of this stuff. Members of the community are assumed to have a certain level of knowledge and direct experience with labels, phantom sensations, etc. Because if someone’s otherkin and they know it, they must have felt certain feelings and read certain information to reach that point. It’s not the same feelings and information for everyone, but people sometimes assume it is.
Another thing is, you probably don’t want people asking your kintype or offering to help you connect to your astral body. Those are nice things to do to an otherkin, but humans can get a bit confused when it happens to them. Humans tend to already be happy with their physical bodies. And I’m not talking about sexual characteristics, I mean stuff like having skin and fingernails and tongues. Disgusting sources of dysphoria to many otherkin, but perfectly agreeable to humans.
