Abstract: | This article aims to explore the argumentative lines employed in an online public deliberation concerned with legislation on same-sex civil union in Greece. Drawing on rhetorical and discursive developments in political social psychology and sexual citizenship debates, the article focuses on arguments regarding the relevance and the implications of public deliberation on the construction of LGBTQI+ claims and rights. The analytic corpus consisted of 1,000 comments, analyzed with the concepts and tools of Rhetorical and Critical Discursive Social Psychology. A recurring line of arguing against the legislation questioned the democratic quality of public deliberation, representing it as a means used to legitimize predetermined decisions. Moreover, overtly discriminatory arguments were predicated on the values of participatory democracy. Accounts in favor of the legislation, though, challenged public deliberation on the grounds that it allows room for the dispute of universal human rights. The potential contribution of these findings to the understanding of the dilemmas of participatory democracy, the reproduction of heteronormativity, and the assimilation of LGBTQI+ claims is discussed. |
