One of the standard ways of undermining any consideration of trans rights, is to focus on the idea that two fixed sexes are a biological reality. Anyone taking this stance because they are averse to trans people is not likely to be persuaded by any arguments relating to that. However, trans people are not the only people hurt and harmed by a focus on the idea of two sexes.
Intersex people exist. If the idea of ‘choosing’ your gender offends someone, then there is none of that argument to make here. Intersex people do not choose. When we focus on the idea of two sexes, we totally erase them. It is a hard enough situation to be in without also being told that you don’t exist.
The idea of two sexes is firmly rooted in white, western culture, and is not a world-wide ‘truth’. When we insist that there are only two sexes, we erase the cultures and experiences of many other people around the world. This is particularly an issue with indigenous peoples who have had to deal with colonialism trying to strip away their approaches to gender – along with the rest of their cultures – for some time. White erasure of non-white experience is something we really need to stop doing.
Many people don’t sit neatly in the boxes offered by the notion of two genders only. My experience suggests that people who do not respect trans folk also tend to have no qualms about harming non-binary people as well – again I think because there’s the sense that we choose. So, let’s focus on the people who cannot choose – the people whose bodies do not conform to gender norms. Women with male pattern baldness and women with beards are perhaps the most obvious examples. The more we tell people there are only two sexes, the more we exclude and disempower people whose bodies don’t fit with that. We erase their complexity and we deny their existence.
Traditionally, feminism has been all about championing equality. I don’t know what to do with the kind of ‘feminism’ that will happily erase people in this way simply to try and create a context that invalidates trans people. However, I think pointing out the erasure of intersex people and indigenous people is really important. Attacking trans people makes it easier to attack other people as well, and if your basis for not liking trans is that you think trans people are choosing, you should be able to spare a thought for people who clearly cannot choose and are being hurt by this ideology.
