Well, here's an example of that anti-nonbinary rhetoric that some binary trans folks espouse but I hadn't encountered in the wild until now. Cis-passing is not a privilege for nonbinary folks any more than hetero-passing is a privilege for bi/pan/poly folks in hetero-appearing relationships or "but you don't look autistic" is a privilege for autistic people. Having your identity trivialized or dismissed by other queer people really sucks.
