“…As noted in Related Work, however, the impact of social media on social movements is a matter of dispute: although some authors argue that the relative ease of virtual participation is a positive development (Etling, 2013;Tufekci and Wilson, 2012;González-Bailón, Borge-Holthoefer, and Moreno, 2013), others question its value (Lewis, Gray, and Meierhenrich, 2014;Shulman, 2009), even going as far as to dismiss it as "slacktivism" (Morozov, 2009) to settle the issue, we note simply that there is a clear analytical distinction between people who protest exclusively through social media and those who participate physically in protests. Physical participation, moreover, also has implications for the question of influence: although social media users are free to engage in conversation with people from different backgrounds, the physical proximity of an actual protest site is more likely to force such engagement (McAdam, 1989).…”
