In the last few years, many countries have introduced (or are proposing to introduce) legislation on ‘conversion therapy’, prohibiting attempts to change or suppress sexual orientation and/or gender identity. This legislation covers ‘aversion therapy’, a form of torture that has already been criminalized in most progressive countries, and also ‘talk therapy’, involving things like counselling, psychoanalysis, and prayer. Focusing on this latter category of practices, I explain what is at stake in the fact that sexual orientation and gender identity have been paired for the purposes of this legislation. I use a particular law reform institute’s approach to this legislation as a case study, and review their literature review in mind to discovering whether they provided sufficient empirical justification for including gender identity in their conversion therapy legislation. I conclude that they did not, and suggest that the pairing of sexual orientation and gender identity may be purely political.
