I'm all about nonbinary people using the terms lesbian, gay, or straight for themselves (I use lesbian and trixic, together.). The problem starts when binary people impose terms onto us.
A relationship between a woman and a nonbinary person HAS to be lesbian. Even if the nonbinary person in the relationship does not see themselves as a lesbian at all. Same for a relationship with a man and a nonbinary person, the nonbinary person MUST be comfortable with being called gay. When two nonbinary people are together, they don't get called enbian or cenelic, instead, binary people make terms up, even when we already have ones.
This seeps into fictional relationships, where a relationship between a woman/man and an enby automatically gets sorted into into yuri or yaoi, or even "yaori" (which doesn't acknowledge the nonbinary identity, nor what would made sense in japanese.)
sorry for ranting everyone... my long text posts (that arent asks) will have the nonbinary banners and proper grammar. banner belongs to @dollixhs ^_^
