I'm not so sure about that - because the younger generation is generally much more aware of non-binary gender trans folks than the past generation tends to be. (With exceptions, of course.) The older guard tend to be the guardians of the binary gender - for very good reasons.
I like the term "trans" - I use that for myself too. Unfortunately, I think anytime a transsexual uses a generic term for "gender variant", the term just sticks to us, as if we're made of glue... (Helen Boyd used the term "trans" to mean anyone who's "gender variant", typically with a non-trivial amount of female identity, but not necessarily a transitioning transsexual. But many of the transsexual girls I know just use "trans".) Anyway, all these distinctions are way too subtle for people who have really no frame of reference for the notion of gender variance at all.
