This forum would certainly be much more interesting if the creationists could ever present a united front, feeding off one another, the way the evolutionists do. But, when two creationists gather, they usually get isolated by different packs of evolutionists into separate sub-topics; or usually give way to a single spokesperson, with the others only chiming in to tell the spokesperson what a good point they've just raised.
This would only be possible if creationists had a unified idea or theory. They are diverse in their beliefs as to what happened when. It is only the "BIG TENT" mentality of fighting against evolution that keeps them together.
As far as posting styles. I usually think it is more appropriate to attack one point at a time in a progressive fashion. Start with a basic premise and continue building on it from there. Many of the creationists get attacked from multiple angles at once. And although i believe there are multiple possibilities to attack, I think it better to focus on one at a time. When their ideas are attacked on multiple fronts they rarely have the ability to comment completely on any front. Then of course, we get the "but you don't understand what I'm saying."
I found all of this very common in Faith's most recent threads. If opponents can focus on one argument at a time and build from there I think it would be more practical. Once everyone focussed on the commonality of mutations and Faith could no longer refute their existence she went into hysteria and just became abusive.
