There are many cooperative people posting here. Their voices tend to be drowned out, some driven away, some dragged into heated debate by the accusers, flamers, bashers, brawlers, etc., so that the perception is that nearly all engage in personal attacks and brawling.
But now, as I understand it, the flamers and brawlers who do not heed the warnings will get progressively longer timeouts until they lose the posting privilege entirely.
Then, and only then, some of the cooperative people who have been driven away will start coming back -- joining those who post well when not repeatedly provoked -- to enjoy an energetic and vigorous but also peaceful and constructive airing of views and differences in which those who are Christians (and those who are not) post in a Christlike and Godly manner and the moderators have nothing to do.
So the last resort need never be, so long as the brawlers who just won't cooperate are not permitted to spoil it for the rest of us.
Let's see what happens to this forum when the brawlers who just won't cooperate are no longer here to stir things up, fan the flames, whatever metaphor seems best.
