Left and right is a useful analytical paradigm, but it's pretty crude. We're thinking about using more pro/con splits instead. But on the other hand, most people think that there is a those people over there who are the problem, and so identifying and humanizing them seems worthwhile.
For example, if someone thinks "The left are evil anti-americas," I want to show them how "the left" can be a reasonable human.
Yet, it's hard for me not to feel like our current situation is ultimately hopeless, with a well-established trend underway of complete disintegration of all social connections and bonds. It may not be long before this internet itself collapses.
We could create viable community again in future, yet all current dominant forces are pushing everyone apart, splitting up friends, relationships, families, cultures, countries, and even dividing us internally within ourselves.
Extremes always eventually flip to opposites, so once this "isolation wave" runs its full course, we may be able to reestablish human to human collaboration again, yet we may not be really "human" at all, by this point.
