If the focus is on enacting laws to make society more accepting of ostracized groups, still the gender nonconformists are a very small minority of those who are oppressed in our society, see lists I've provided.

Now, if you are only focused on repealing laws, then you might have a case, but a lot of the gender nonconformist activism focuses on positive laws and other forms of punishment on those who don't accept them. So, insofar as there is a positive push, then it is only a small interest group out of the suffering multitudes that are benefited and my case stands that the focus on gender nonconformism is myopic.
