OK I don't get this. So because someone says something enough it overrides what is considered correct? "I could care less" is the common usage of the actual phrase "I couldn't care less" The word "Aks" as in "Let me AKS you something" is incorrect, so we should throw out the correct usage because it is common?
Why does WPATH get to define the word? Because in the world of science we need words and phrases that everyone agrees on to communicate. WPATH is the group who is foremost in the Trans (oops..sorry...that slipped out) world. When they invented cars someone called the piece that sucks air and mixes it with gas a carburetor...so every mechanic could communicate that instead of saying "that sucky thing". Who if you don't think WPATH has the right, does have the right to make a word that will define the gender dysphoric community? Just because a word is used commonly...doesn't make it correct.
And why should we start excluding sections ( ie fetish dressers)? You start with one group ten it makes it easy to exclude others
