Carl Sagan wrote "The Demon Haunted World" before he died. In it he talked about what your comments address - that society was becoming 'all or none' in its approaches to issues, with no compromise or willingness to examine and discuss.It may always be like that. We just go through cycles. Look at the American Civil War. Or the Spanish Civil War.
Sometimes it's all about timing and the issues emerge and there you go. Fireworks.
