You know, I think it is always part of the conservative-reactive view of the world to be suspicious of differences. To attempt to protect a concept of “normal” — which of course depends upon identifying a contrasting “abnormal” and then allowing fear, disgust, discomfort to encourage social norms and even laws to fence out people whose authentic self-expression places them in one or more categories of “abnormal.”
I am saying that, by all of us who are already corralled in the “abnormal” ghetto AND everyone who wants to recognize all these differences as part of intrinsic human variation, defining ourselves as “transgender” we are taking away the power of those who want to use it to divide and conquer. Because “trans” implies a spectrum of human variation, and claiming it proclaims everyone’s right to be who they are and denies any utility or rational excuse for such things as “bathroom laws” or a need to carry one’s birth certificate at all times out of the need to protect oneself. If we are all “trans,” we all have a right to live as neighbors among all human sexual varieties of expression; to change as change occurs within us; to dress and behave in ways that reflect our self-perceptions. We do, as a society, have the right to outlaw behavior in all realms that is exploitative, abusive, coercive or violent. But this right exists because no one has the right to treat another this way.
Conservative people who express conventional sexual identities, behavior and practices are not under attack. I see the proliferation of efforts to marginalize, even criminalize, differences as attempts to use their power against groups of others without needing to justify them by any truthful appeal to broader standards of harmlessness or fairness. I also think we who are thus discriminated against do not help ourselves when we allow ourselves to be “sliced and diced and set against each other.” Solidarity recognizes us all as human, whatever point on the spectrum of sexual identity we occupy. That, as you said, our commonalities are more important than our differences. A curious and open query into the value of difference would be much more helpful than resorting to stigmatizing those different from us, attempting to force people whose difference we do not understand into our own mold, and whipping up fears without facing them as our own problem.
