A strange thought entered my head this morning: We have not been seeing a rise of this or that ideology per se over the past few years. Instead, what we have been seeing is an increase in *possession by belief,* which takes many forms. Possession itself is what's on the rise.
Myself and many people I know in my democratic have worked their way through a number of extreme and ideological positions. People are more likely to have extreme, fringe beliefs, but loosely held.
