i personally use "trans" as an adjective, and use it to denote anyone who can't say for sure that they're perfectly cissexual in any and all ways.
this is because i like terms that look like and can be used as (practical) words of a language.
trans* has two weaknesses the way i see it.
one is that it isn't a word ("*" isn't a recognized letter of the english alphabet at least). talking about people as [this isn't even a real word] feels odd.
the other is that the asterix is a widely recognized wildcard, and anyone who has the slightest knowledge of the use of wildcards and does not know the history of the term, will automatically start including all words that start with "trans", while also excluding everything that does not start with "trans".
when i read "trans*", i do this, and can't really help myself or stop this from happening. i read trans, transgender, transsexual, transmission, transylvania, transatlantic, transcriber, trans-siberian... and find myself including things that aren't supposed to be included while excluding things it was meant to include.
a whole nother thing is that language is dynamic and constantly evolves. unless it dies, which is a real tragedy.
what was a word yesterday may not be a word today, and what everybody mocks as ridiculous today may be a common word tomorrow.
a word's meaning also changes over time. this has proven somewhat problematic when reading old books (like the bible), because of terms such as "effeminate" which once upon a time meant a man who loves women a little more often than he should, but now somehow happen to mean something quite different and almost opposite of the old meaning.
how a word is used, will in the end determine what it means. no matter the intentions were when it was created, it's how people use it right now, today, that really matters. even "sunflower" can become a cuss word if people start using it as one. some friends of mine once unintentionally proved this point by trying to replace cuss words with the name of a poor little flower that started to sound very derogatory to the users after only a couple of weeks of trying not clean up their language a little.
discussing how we use words, and the intentions our causes behind our own personal language usage, is still worthwhile though. it is never bad to be conscious of how we use language and how it affects others.
