A blunt summary of the concluding point of the previous post is that gender does not exist except as a tool of oppression and a cultural fiction.
Proper conceptualizations of any given phenomenon must eschew patriarchal language. To my absolute horror, I have read people try to paint butchness as a “gender identity,” usually some type of transgender. Aside from the fact that (in the U.S., at least) butchness does not have the cultural stamp of approval that is the fundamental component of any gender, and is thus not a gender at all, the term “transgender” is problematic from a feminist perspective because it defines people in terms of the patriarchy’s (fictional, harmful) categories. It reifies gender with the claim that those so labeled transcend/cross/etc. it(depending on the sense of “trans-” implied). While it is sometimes useful to describe using patriarchal terms in order to underscore opposition to the default or expected patriarchal order, there can be nothing healthy about a personal identity or a definition expressed or conceptualized in patriarchal terms. Besides, the patriarchally-brainwashed point out that butches aren’t like “regular women” every chance they get – they don’t need the help.
Perhaps more horrifying is the use of “butch/ftm,” as if there is some sort of connection between the two. This sometimes rests on the idea that both butches and ftms exist on the same “spectrum.” Spectrum of what, though? Some say masculinity, but, masculinity being nothing more than a patriarchal wet dream, no such spectrum exists.
