The ‘Social networks and activism’ round table focuses on the strategic use of social networks to advance left-wing ideas. Speakers discuss the ways in which these platforms can be used to mobilise, inform and unite support around left-wing values. The emphasis is on creating engaging and hard-hitting content, using virality to reach a wide audience, and building authentic and transparent communication to counter misinformation. The aim is to show how social networks can be a powerful tool for strengthening the left, broadening its activist base and, ultimately, winning over its ideas in the current political landscape.
