The paper appears to adopt, as its starting premise, an unduly narrow description of what they refer to as the expansion in the term transgender - by failing to mention that the ‘many other subjectivities’ now covered by the term transgender include erotic cross-dressing.
“The term ‘transgender’ was introduced in the 1990s and, as described in more detail later, has gradually developed into an umbrella term that encompasses many other subjectivities within the concept of gender identity, such as genderqueer, genderfluid, agender, and non-binary, and regardless of whether individuals experience gender dysphoria or desire or undertake medical or social transition”
If the paper ignores the motivations of erotic cross-dressers as one of the factors to be considered when assessing whether women’s single-sex female-only facilities and services should be permitted to exist or should be withdrawn from women and transformed into mixed-sex facilities open to males, then the paper will be of limited value for use in policy-making.
Or more accurately it will be of high value to those males wishing to have access to facilities and services which are currently single-sex female-only provision. But of limited value other than for that purpose.
