Underground movements percolate
One of the more interesting things is how much stuff goes on without the mainstream noticing. One of those in the past 3 years is the growth of fascist and quasi fascist ideologies in a 21st century context. It's still not understood out of certain internet circles how much that contributed to the Trump win ( a lot is the operative estimation).
The other thing that's percolating right now outside of sight is a serious interest in Communism (other socialisms too, of course) and developing a new and more functional political programme around that.
