The price of terminology

From looking at the Benjamin scale the tipping point of his patients for the questioning of birth sex was after his Type II. Beginning at type III his patients ruminated over what to do about their feelings with increasing frequency and seriousness. Types I and II seemed fine with expression with only the frequency varying between each. What they suffered primarily from at that time was shame and guilt and not necessarily a core identity disconnect. 

In that sense I don't see a hard stop between what was then referred to as tranvestism and transsexualism (the signs of which began according to Benjamin at his Type IV). We could then say with some confidence that we were always looking at a gender dysphoria intensity scale from almost none on one end to the very intense variety on the other. The hard dividing line was really about who in Benjamin's time would transition versus who wouldn't as the half measures of today were much more rare.

I sometimes see comments like this:

"Don't ever tell people that you are a crossdresser but instead transgender" which deals with the baggage of terminology increasingly falling out of favor. In the end both of those terms have been exceedingly elastic the whole time because the lives lived underneath each aren't all the same. 

Such is the price of generic terms being used to capture a large and diverse group.
