people get hung up on words because we use them to define the world and ourselves.
i am also one of those who don't really care all that much, unless people try calling me weeaboo.
but there is still the fact that people use words to identify with, or as different from.
ust like some lesbians back in the day felt a need for a different word than that which gay men use to define themselves, many trans people also feel a need to identify as something other than anything that starts with "trans". it's a funny thing how important words become when they feel wrong. i know how odd it is to be called daughter, and you probably know why you don't find it right to be called a man.
many trans womem would rather be known as woman rather than transwoman, the same for trans men. and there are a whole lot of other things to consider too, like how the usage and grammar of a word can change over time, as people find ways to use them that fit better with the reality they live.
this whole thing about trans and trans* is difficult for me to explain with words. i tried drawing the feeling i got, it fails partly because of handwriting, partly because "everything that" was not written out before taking a pic. it's supposed to read "everything that starts with 'trans'".
now this is only the feeling i have, of where the problem lies. it is not an answer, nor an accusation. just me trying to express what i think makes the wildcard look wrong to some. i do not believe it was ever intended that way, but just like with all words used to sescribe people, it can easily fail. the original word for my own ethnicity is now considered a derogatory, just the same as indian, eskimo, negro, ->-bleeped-<- etc. trans might end up there one day too, depending on how the trans society will feel about this word and its usage in the future. we can't know that now, but discussing words when a group find them problematic, is always worthwhile, unless we wish to exclude or other a minority group.
