Yes, absolutely dismantle the gender binary. BUT dont forget to dismantle the sex binary too. Intersex people exist and they regularly get ignored in both queer and non-queer spaces. There are NOT only two sexes, and us perisex trans people CAN NOT forget that or else we will become like our oppressors, people who say there are only two genders and that what you are born as is what you must stay as. Intersexism must be stopped.
