That's correct. I don't think there's anything "trans" about crossdressers -- at least not ones like you who identify as 100% male. But you should be glad to have the LGBT community on your side. You should be glad that the blanket term "transgender" is generally seen to include you, even if it's not really the best term to use.
Yeah, let's talk about being "true to ourselves"!
So, you're so far in the closet that if you were "outed," you would be so ashamed of who you are that you would be more concerned about the reaction of your family/friends than you would about losing your job? That must be a fun place to be at psychologically where you don't care about your civil rights, you don't care about being treated as human, you just care about being able to hide who you are. Maybe it's good that you don't associate with all the people in the TG community who are fighting for the right to be true to themselves.
That's not really what you meant to say, is it?
So the point's moot, then? Because unfortunately gender identity is not defended like sexual identity is. You can get fired for being trans. You can get banned from using the proper restroom. And you are not protected from hate crimes. Victims being "transgender" are not even reported most of the time, so we don't even have the real statistics of crime against trans people.
To the contrary, the "trans-panic" defense has gotten some murders reduced to assault charges, because apparently we're such an abomination that it is totally understandable for someone to murder someone who is a freak.
