Recently I listened to an episode of This American Life entitled “White Haze” about various Alt-Right and Alt-Lite movements, and the Venn diagrams of belief systems that may or may not include men’s rights, reclaiming traditional masculinity, abstaining from masturbation, anti-PC/SJW, keeping women out of the workforce, opposing non-white immigration, drinking beer together, anti-Semitism, white nationalism, casual racism, and full-blown white supremacy.
My impression was that for many members of these white male conservative groups, the main emotional issue was a sense of entitlement, manifesting as resentment and finger-pointing if such things as girlfriend, job, wealth, and status didn’t easily materialize. That, and an imagined sense of cultural oppression by liberals and feminists (though specific examples of how exactly white men are oppressed are elusive).
