The question of scale is extremely relevant here. It's a well-known phenomenon that as organized/structured entities grow, there are certain thresholds at which they transmute - the structure itself changes to support the new level of scale. In terms of human groups, we've traditionally dealt with this by means of hierarchies (with all the built-in shortcomings). Personally, I find a homogenous mob terrifying. Being in agreement with millions of others implies that the subject of the agreement is extremely basic and common (like "we all need air to breathe").
