Based on a qualitative study of Copenhagen 2021 WorldPride, this article explores collaboration between the local organiser and its corporate partners, focusing on the tensions involved in this collaboration, which emerge from and uphold relations between the extremes of unethical pinkwashing, on the one hand, and ethical purity, on the other. Here, pinkwashing is understood as a looming risk, and purity as an unrealizable ideal. As such, corporate sponsorships of Pride are conceptualized as inherently impure—and productive because of their very (...) impurity rather than despite it. Analytically, we identify and explore three productive tensions where the first involves emergent normativities for what constitutes good, right, or proper corporate engagement in Pride, the second revolves around queer(ed) practices and products that open normativities, and the third centres on the role of internal LGBTI+ employee-driven networks whose activism pushes organisations to become further involved in Pride, developing aspirational solidarity. Reading across literatures on corporate activism and queer organisation, we introduce Alexis Shotwell’s notion of constitutive impurity to suggest that the potential for ethical corporate Pride partnerships arises when accepting the risk of pinkwashing rather than seeking to overcome it.
