Ash, what's your problem with the Chairs case, other than the fact that "It's a convenience lynch"?
Basically, my reasoning for thinking Chairs is scum is that he scummily sheeped onto you during your self-voting period. He voted while saying things like "I'm going to be miffed if you guys are right and he's just doing crazy things", which indicates either a good deal of uncertainty, or knowledge that he's wrong.
He voted Voltaire initially, only saying "Gut alarm". He said he would back up his gut feeling with a re-read, but didn't. He unvoted while TA was tunneling, which tells me that he's aware of what others are thinking of his votes, and is concerned with not appearing towny. He unvoted immediately after TA said, "I'm uneasy about both of these lynches", saying "Perhaps TA is right and I'm tunneling." If your read was weak enough that all it took to get you off of it was another player saying "I'm uneasy about this", then why you were voting in the first place? I'd be willing to excuse this if there wasn't already votes on Voltaire, but I don't think town wants to be voting on a very weak read when they're the third player on a wagon.
Mainly, he has twice joined wagons without a good reason, and has expressed uncertainty about those wagons. If he were town, I think he wouldn't be joining wagons where he has such uncertainty about the person he's voting. If he was town, I suspect he would be more careful with voting for players who already had other players voting for them if he reads really were as weak as he's acted like they were.
I'm also concerned with his tone towards Voltaire in #751. I think it's unlike anything I've seen from Chairs in other games, and Chairs in other games has been town.
