I’m a straight cis white male but it’s only relatively recently that I’ve begun to think about myself using these labels. One of the surest signs of privilege is not having to think about your identity, to be sure you’re an individual and judged like that by those around you, not having to have to construct labels to explain yourself to others.
Which is why something like “cis”, a seemingly innocent counterpart to “trans” in the context of gender identities, similar to how it’s used in frex biological chemistry or when talking about cisalpine and transalpine Gaul, has been greeted with so much venom and outrage even in supposedly liberal environments. It rubs the noses of everybody who thinks of themselves as normal and trans people as the outliers in the fact that their gender identity is just one possibily, not as matter of fact as they’d want to.
In leftwing circles there’s long been a tendency to bewail this sort of identity politics, the endless parsing of possible gender or sexual identities, the splintering of groups into finer and finer subgroups, but I more and more think this is as much a good thing as a bad. First of course, for any oppressed or invisible group getting that identity established is a way to become visible, but second, it also shows up the unnaturalness of the default assumptions about people’s identities. The more we all realise you can be homosexual, bisexual, asexual, etc, the less “normal” being heterosexual becomes.
