Snow: The desire to end the theory talk is because it's presence can hurt the game. When we're talking about theory talk, scum can easily slide in and talk about theory, because they don't have to take stances on players, yet remain active. Once we're done with theory talk, we're going to be voting, talking about votes, etc. and those are going to be useful information later. Right now, scum can easily slide in and be honest, because it's so easy. Once we get past theory, scum have to manipulate information in a certain way that town don't, and hopefully we will catch them doing so.
Ash's desire to move on isn't saying anything about the hider plan or its merits. Personally, I think it's a good idea, and don't blame the people who brought it up. But we're playing this game with a lot of people who can talk a lot, and if we don't watch ourselves, we'll end up 25 pages into this thread and absolutely no closer to lynching scum, which makes re-reading harder, and just makes the game less fun. It's just in the best interest of both the game and everyone's level of enjoyment to move the game on.
If you want to find Ash and Shraeye scummy for opposing a good plan, that's your choice. But I think they're trying to get the game away from theory talk because honestly, it's not fun for a lot of people. And I don't think that's based on alignment at all.
