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

For example, during covid I believe the anti vaccination movement was largely about community and only tangentially about political goals. Especially because it was an otherwise hard time for people to interact.

It's probably largely the same for the maga movement, the rationalism movement, etc.

It feels nice to be a part of something and to be able to identify with something and such movements tend to easily accept new members as long as they at least aesthetically support the same cause.
