>Do you feel that politically "extreme" movements are a reaction to that and actually mostly about community and community interaction?

Yes. Great writing on this from Jonathan Haidt (The Righteous Mind), Robert Putnam (Bowling Alone) and Ezra Klein (Why We're Polarized) and Vivek Murthy (Together). Haven't read these, but I've read about them. One of their main ideas is that when people lose trust in institutions and feel disconnected, they’re more likely to embrace extreme ideologies or groups that promise belonging.
