Yo just so you know two spirit has nothing to do with furries. It usually refers to gender nonconforming traditions in indigenous american communities and has largely come into favor in Canada as part of recent campaigns to recognize tribal communities and their histories.

Otherwise, I think you’re thinking of “otherkin” who are not generally included under the LGBTQ umbrella, but are frequently brought up to discredit queer progress as a movement.
