Economic frustration will likely manifest as anti immigrant sentiment. Extremist groups provide inclusion as a cure for social isolation. Degrading healthcare systems are fertile ground for anti-vax and pseudo-medicine. Digital echo chambers give a space to amplify every toxic narrative.

Occam's razor says the guys preaching the fatalistic misogyny gospel are probably experiencing some strong sexual frustration. If they didn't have that problem they could find something else to be mad about.

No toxic ideology precludes the others, but a racist with a stable marriage isn't going to be blackpilled. He already knows minorities are the real problem.
