"When we talk about trans people, we’re usually referring to individuals who were either recorded as male at birth but who understand themselves to be women (trans women) or, vice versa, were recorded as female at birth but who understand themselves to be men (trans men). Not all trans people, however, find simply moving between the pre-existing categories of man and woman satisfactory, accurate or desirable. Such trans people, who are less well understood, generally unsettle mainstream society more than trans men and women, because they challenge not only the prevailing idea that birth genitals and gender are inseparable, but also the idea that there are just two gender categories. Often, these people are accused of making up their experience out of a need for attention or a desire to feel special – though in reality the political, economic and social costs for such ‘non-binary’ trans people (who don’t straightforwardly see themselves as men or women) can be immense."
