Transgender was intended as an umbrella term, then a name of inclusion. But umbrellas don’t work well when one group holds them up. Today, trans activism is often focused on the problems (bathroom access, name change, workplace transition, and hate crimes) faced by those who have been most active in its success: postoperative male-to-female transexuals (any similarity to the author is purely coincidental).
Yet there is little being done today to address the needs of drag people, butches, cross-dressers, transexuals who do not seek surgery, or (besides the Intersex Society of North America) intersexuals. Cross-dressers especially have suffered from lack of representation, although they number in the millions and experience severe problems associated with child custody, job discrimination, hate crimes, and punitive divorce precedents.
Thus has transgender, a voice that originated from the margins, begun to produce its own marginalized voices.
