Not only that, but said religion(s) encouraged internal debate/conflict and unity alike, rather than push away everyone who deviates from the norm in any way.
As it goes, its much more fun to have little factions within a faith than to force a schism and see old (possibly new?) faith(s) weakened as a result.
Sorry if I'm tooting JV's horn, but the whole OS thing is a damn fine example of chaos within order, unity within strife.
May it grow to SA proportions some day.
