Polemical social representations about "immigration" in journal articles of different political positioning via Facebook

Among the different social discourses diffused through the Internet - and in particular the social media - this contribution focuses on immigration as object of perceptual distortion and ideological polarization through the lens of Facebook. The diffused perception of the immigrants as the "others", the unknown, foreign is often assimilated with dangerous, extraneous and generally presented in the media as invaders, or stigmatized as potential terrorists, legitimizing fear and evoking the need for barriers and protection of the own territory by the population of the host country. On the other side they are perceived as social victims or marginalized groups. Within a wider research program including interrelated ‘field’ and ‘media' studies, this contribution is aimed at detecting social representations and attitudes according to the different ideological positions and identity affiliations, which guide the processes of social inclusion/exclusion towards immigrants through the analyses the political discourse via FACEBOOK (among other social media analyzed: Twitter, Youtube, Instagram) and a rich set of complementary sources from multi- voice and multi-agents (scientific, institutional and lay people) discourse (de Rosa et Al,, 2019, 2020a, 2020b) .
