People can be true to a team and end up chauvinist; or they can be true to an idea and end up ideologues. The point about extremists getting their opinions in bulk is a solid one. I'm not so sure intentional moderates is a well-defined category. It's what most "balanced" media strive for, but it's more like rubber banding in a video game race - the media have incentives to ensure an exciting, tight race, it improves their viewership, so they try to find the dead centre. I think what PG calls intentional moderates are simply not that interested. Also, I think accidental moderates can end up fairly extreme in the end, because tribalism is ultimately a very strong draw and critical thinking is tiring.
