The term itself is next to useless at this point because every time I have to use it in debate I have to then immediately make the distinction between several groups who are not the same but assumed so because of this very word. I.e.- the difference between transgender and transsexual, or cross dressing, or non-binary, or non gender conforming, and so on.
This is why the grammar of the word doesn't matter, the word itself has become almost redundant in political conversation unless you are going to lump all those people into a single category which if you have any attention to detail is poor form, in my opinion.
Hence I use the term transsexual far more than this one when referring to myself and people like myself because at least it describes something specific and defineable. "Transgender" could almost mean anything by now. I've seen people describing themselves as transgender who show no characteristics of being transgender other than having blue or green or pink hair and a punk dress style or being in a particular mood that day. What good is the word if it means whatever the speaker wants it to mean?
How do I feel about the word? It's inadequate. I spend so much time having to go into details after using it that it is no longer expedient to use it.
