A flamewar is not a real connection of opposing sides that lets each understand the other, it's a progressive back-and-forth of increasingly simplified versions of the other's position until both sides hate each other more than when they started. It's still a part of the echo chamber phenomenon; just because there are people who hate each other shouting at each other, doesn't mean the inherent structure of the medium won't make each more rigid in their views.
