43. Digital campaigns of hatred and destruction, for their part, are not – as some would have us believe – a positive form of mutual support, but simply an association of individuals united against a perceived common enemy. “Digital media can also expose people to the risk of addiction, isolation and a gradual loss of contact with concrete reality, blocking the development of authentic interpersonal relationships”. [46] They lack the physical gestures, facial expressions, moments of silence, body language and even the smells, the trembling of hands, the blushes and perspiration that speak to us and are a part of human communication. Digital relationships, which do not demand the slow and gradual cultivation of friendships, stable interaction or the building of a consensus that matures over time, have the appearance of sociability. Yet they do not really build community; instead, they tend to disguise and expand the very individualism that finds expression in xenophobia and in contempt for the vulnerable. Digital connectivity is not enough to build bridges. It is not capable of uniting humanity.
