Personally, I know the psychological outlines of being diagnosed with TS, and I personally do not fit the criteria because, quite frankly, the criteria fits someone with the IQ of a 13 year old.
For instance, there seems to be a line saying that a person cannot want to be the opposite sex for sociologically beneficial reasons. Well, to be honest, sociology is one of my favorite subjects and I know every percentage and statistic behind the advantages, disadvantages, and perceptions of being male and female, and that's just because I have a high IQ in the subject itself. Because I'm factually smart, I cannot not include certain sociological benefits in my ultimate goal. I'm not a kindergartener who says "I want to be a girl cuz God gave me the wrong body on the outside!" I don't think I was that stupid even when I was 4, I'm simply not a religious person. I don't believe in "souls" or "gods", I believe that I was born with a chemical imbalance in my brain that allowed me to see the benefits and attractions of aligning my body with my personal interests, goals, romance role, aesthetics, and attitude, which, by definition, is being and looking a woman. I care about much, much more than genitalia, because quite frankly, according statistics and science, what genitalia you have is much less important than what face or body shape you have, according to again, various studies and surveys. If my TS disorder is more align with modern science than the TS disorder of someone born in 1942, then that's not my fault.
However, as long as it still qualifies me for hormones, I would not mind at all being diagnosed as TG instead, and I think I do fall under that definition more specifically.
