Welcome to evcforum. As a former Aussie, it's nice to see a Kiwi joining.
I haven't thought much about your list, although it seems to be roughly right. What happens mostly, is that creationists join the site fully determined to refute evolution. Then they come face to face with the problem that evolution really is well supported by the evidence, and those obvious refutations they had been taught simply miss by a mile.
The debating is a lot easier for the pro-evolution people, because the evidence is on their side. The effect is that the creationists become increasingly frustrated and emotional, while the evolutionists are usually able to keep their cool.
I think, if a creationist were to join the site with the aim of simply joining the discussion (rather than refuting evolution), they could actually have a reasonably pleasant time. But that is not the way most creationists approach the site.
