TLDR: "Today’s rightwing populists have proven so successful at appealing to those for whom the traditional bonds of the workplace, religious institutions and the wider community have broken down. Their success also lies in this: an appeal to the feeling of exclusion and marginalisation that many citizens have come to experience in recent years, a sense of being ignored, even abandoned, by those who hold political and economic power."
The logic seems to argue more that outsiders will appeal to the lonely.
