This article develops a theoretical framework to understand how sexuality can be institutionalised through debates about marriage equality. We first examine 13 Australian sporting organisations concerning their support for marriage equality and sexual minority inclusion before showing they drew cultural capital from supporting episodes of equality exogenous to their organisation, while failing to promote internal inclusion. We use online content analysis alongside the identification of institutional speech acts within policy to analyse results through three conceptual lenses: Ahmed’s institutional diversity work, Ogburn’s cultural lag, and Evan’s organisational lag, from which we propose a hybrid – organisational cultural lag – as a theoretical tool within social movement theory.

本文建立了一个理论框架，以了解如何通过关于婚姻平等的辩论将性行为制度化。我们首先研究了13个澳大利亚体育组织在支持婚姻平等和性少数群体包容性上的作用，然后证明它们从支持组织外生的平等事件中汲取了文化资本，却未能促进内部包容性。我们将在线内容分析与政策中的制度性言语行为识别结合使用，通过以下三个概念来分析结果：艾哈迈德的制度多样性工作，奥格本的文化滞后和埃文的组织滞后，从理论上我们提出了一种混合-组织文化滞后-社会运动理论中的工具。
