Someone said WPATH is living in the past. That's undoubtedly true. I think what has to be remembered is the members are steeped in science. Absent scientifically derived evidence showing RLE is a waste of time, nothing will change. Either scientifically prove your hypothesis, or get over it.
I think part of our issue has to do with calling the MtF operation Gender Reassignment (or Confirmation) Surgery. Our gender is who we are; it's what's between our ears, what we know of ourselves. To us, there's no doubt about our gender, and no surgical procedure can enhance that. Whether we present as femme-fem or butchy-butch, our gender is our gender.
Conversely, walking around with an exposed vagina isn't how society classifies one's sex (that's sex as in the marker on your driving license) as female. Our sex, generally defined as genitalia, can be changed with a surgical procedure which some of us feel is our (constitutional/god given — take your pick) right to have on demand. But it won't make society classify us as woman, rather than man, because it's invisible unless naked.
So I'm torn. I get there are gender-queers who should have every right to a body of their choosing. But there are also those who intend to socially transition, and SRS is at the end of the process not the beginning. WPATH will never accommodate those who don't intend to live as a member of the sex not assigned at birth (unless you get data confirming that hypothesis). The only solution is to fake it. Show up at the shrink in convincing girl drag. Have a believable story.
I know I'm repeating myself, but the SOC, from Benjamin to WPATH, were designed to insure the best outcomes for those planning to live as women within society. They're not equipped to deal with the minority who are just uncomfortable with their birth-body. I don't have a clue how to resolve that.
