The last few years have seen the development of a new line of research around the relationship between digital platforms and activism. The influence of the internet and social media on the civic and political engagement of young people in particular has become clear. Digital platforms perform in this regard a set of functions crucial to activism in terms of communication, mobilization, and logistics. These are indispensable tools, especially to young people belonging to informal structures. Digital platforms have also been (...) shown to facilitate emotional and solidarity networks thus fostering a sense of community and a strengthening of collective identities. In this article we aim at examining this aspect based on in-depth interviews with young activists conducted in Portugal during a three-year project (2020–2022). We have concluded that, especially in certain activism contexts involving social groups of neglected or non-normative identities, digital platforms function as a crucial empowerment tool. These are linked to the emotional support for and recognition of the identities of these young people, incentivizing the creation of fields of political and social intervention. (shrink)
