This is not a joke. This is an observation by sociologist Michael Kimmel, author of Angry White Men: American Masculinity at the End of an Era, who tells the UK Guardian that the angry manly rage that fuels both ISIS and Trump stems from a sense of smallness:
One of the most prescient observers of violence I’ve ever read, James Gilligan, wrote a book called Violence. He argued that shame and humiliation underlie basically all violence: “Because I feel small, I will make you feel smaller.”
In my interviews with extremists, both “actives” and “formers”, I have found time and time again that they have experienced that sense of humiliation and shame.
In his famous statement, Osama bin Laden talked about how the west had humiliated the Muslim world … that conservative Muslims have been humiliated by hyper-modern society and the cosmopolitan McDonaldization of the world. For them, restoring the seventh-century caliphate is their way of reinstating traditional masculinity.
I call this “aggrieved entitlement”. If you feel entitled and you have not gotten what you expected, that is a recipe for humiliation.
…The camaraderie of the community validates their masculinity, and – even more importantly than that – gives them a sacred mission. That is really powerful for these guys [J. Oliver Conroy, “‘Angry White Men’: The Sociologist Who Studied Trump’s Base Before Trump,” UK Guardian, 2017.02.27].
When a group—for example, South Dakota Republicans—goes looking for someone to pick on—for example, refugees, gay parents, non-Christians, environmental protestors, low-wage workers—that’s a fair sign the group has some issues of its own it needs to work out… preferably in some way other than passing offensive legislation or electing an unqualified President.
