Subversivism: Sexism that is rooted in the presumption that genders and sexualities that are deemed subversive, radical, or transgressive are inherently superior to those that are more conventional. While this form of sexism is not prevalent in mainstream culture, it does proliferate in queer, feminist and radical circles. - Julia Serano
The gender binary hurts us all by instilling gender expectations and promoting sexism, homophobia, and transphobia. Thus, it's completely acceptable for anyone to be frustrated with the binary and to want to smash it (I know I do!), it's completely acceptable to experience anxiety and discomfort with hegemonic gender expectations and scripts, and it's completely acceptable for people to dislike pronouns and labels. In fact, I think all of us should actively pursue a post-gender world. However, appropriating genderqueer identities is not the way to do so. Appropriation is harmful to all people, cis and trans, binary and non-binary.
I've feel like I've covered some sketchy ground, and it's important to once again clarify that no one should ever accuse anyone of not really being genderqueer, bisexual, or any other identity, and a person's pronoun preferences should always be respected. However, I also think it's important for individuals to consider the things they say and why they say. As the article I linked at the beginning explained (and if you haven't read it yet, go do it immediately), appropriation of genderqueer identities is harmful to everyone, and should be avoided. In my community, I've seen first-hand how such appropriation hurts many different people.
Edit: I edited the fourth paragraph because, upon rereading it, I found some of the things I wrote problematic and inconsistent with my actual opinion.
