A thought about why I prefer some (RL and internet) discussion environments

It occurs to me that the sort of social environment where I prefer to have conversations, face to face or online, can be summed up in this way:

A (puts forth a view or observation)
B (counters in an assholish way)
A (ignores what B said, because nothing good will come of rising to B’s bait)

An environment where B is not considered by others to have won the argument by default, is the place and the people I like to be with. The SDMB is one of these places.
