Will the Left Isolate Itself into Irrelevancy?
I have noticed a trend. People on the left tend to surround themselves with like-minded people, which, by itself is not a problem. Everybody tries to do that. But when they block anyone with an opposing viewpoint, they not only block opposing perspectives, they also block themselves from influencing others. This could be a problem as the left's perspective becomes less and less visible and influential to the masses.
