Trump received more support from white men than any other group in the presidential election, but this was expected, at least according to sociologist Michael Kimmel. His research is part of the new but growing field of “masculinity studies,” and in a recent interview with The Guardian, he talks about his book Angry White Men: American Masculinity at the End of an Era. His research specifically looks at how people join, and leave, white-supremacist or neo-Nazi groups, and he states that masculinity is an important part of the process.

Kimmel talks at length about many parts of this picture, including the men’s rights movement on the Internet, the role of testosterone (or the lack thereof) when it comes to men being disproportionately aggressive, and why “men are naturally aggressive” is a poor argument to defend domestic abuse.

In the interview, Kimmel explains how feelings of “aggrieved entitlement,” a sense of a loss for masculine power and tradition, can stimulate feelings of humiliation. In turn, this can drive men to join local neo-Nazi groups. There, the camaraderie and sense of community can validate a neophyte’s masculinity, convincing him to stay. In essence, masculinity is very tied up in how people join and leave hate groups and extremist enclaves. As Kimmel states,

“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 … If you ignore masculinity in understanding how these guys get into these movements, you will not be able to help them get out.”
