I think they are mostly voting based on area of concern #2, in that Argon is a notorious fountain of chaos that whoever the wolves are they can use for cover. But he is, in my opinion, lacking in the other two areas. He hasn't done anything genuinely wolfy, he's just been himself (meta), or just been a day one player fooling around since there's nothing to go on anyway (nonmeta same thing). No one who has defended him is cleared if he flips town, and no one voting for him is suspicious if he flips town, so there's minimal info gain from lynching him.
