I think it's a mistake to judge intra-community fights based on sample sizes of a single discussion. Much like domestic arguments, the surface disagreement is often not what the fight is really about, and it's not easy to understand it without knowing the context, how long the forum participants have known each other, how disagreements have played out before and so on.

There are a lot of unwritten rules and informal relationships in any forum with a persistent membership, and in my experience it takes months, sometimes years of observation to be able to read them accurately.
