You're saying you think it's a weaker reason to lynch someone than "based on an assumption about the Snowman which has subsequently been explicitly refuted by the narrator, Extrail must be lying"?

I have no particular brief for Extrail--they've talked so little I can't tell whether they're likely to be a wolf or not (which is itself mildly suspicious)--but what's your reason for keeping your vote? Because as far as I can tell, it amounts to not taking in anything contradicting your initial assumption.
