Anti-discrimination work increasingly involves digital social movements and new technologies that connect local social justice issues to transnational ones. This chapter explores the role of the hashtag in transnational social justice movements by considering the #BlackoutTuesday campaign, which occurred in Spring 2020 during a resurgence of the Black Lives Matter movement. The #BlackOutTuesday campaign is explored beyond a tool for participation in anti-discrimination work and rather as a co-produced transnational frame of protest. The movement is further discussed as a case of digital praxis of allyship and activism, which results in an online site of dialogue, constructed community and flexible interpretation of the movement. The latter included widespread performative participation and interpretation of the movement co-opted the original intent obscuring information for activists. As usage of social media and hashtags within anti-discrimination work grows, it is important for scholars to consider the ways in which these platforms frame allyship and activism. Hashtags, as examined in this chapter, provide a space for communities to form where dialogue takes place and one’s role in social justice is explored. Yet, the ways in which people participate may not translate to furthering social justice and may actually contribute to upholding white supremacy.
