We can start by not separating everything into two sides, one of which we must take. Look at each conflict as a whole rather than a sports game with a winner and a loser or a Good and an Evil or a My Team and Their Team. Maybe one side really is actually very bad and needs to be stopped. Maybe there are other ways.

There are times when this is true and admirable - "us vs them" rhetoric in political discourse is indeed harmful and only serves to help those in power - but there are times when it's more dangerous to treat both sides as equally valid that we should both listen to - like when a superpower invades another country and wages a war for years.
