Don't think you've been back long enough to determine that, Monketh.
I'm not saying Bilbous isn't argumentative, but he's somewhat rational, as well.

Seytra and Kiern aren't argumentative in the sense that they go actively seeking things to argue about in threads that don't require any arguments... Also, they're not around enough to be in the running... I'm still voting Zanzibar, but Datruth is trying hard, too.
