It seems very strange indeed.I can see why it would look strange. Consider my perspective though: I know that I am town and that Ibarra is scum. So why would I consider the scenario where I am lying? I was merely adding an argument for why he would be scum if you don't take my word for it. Though yes, if I really were scum, I would only need one townie to mistakenly vote for him and my buddy could quickhammer. That's not what's happening though. I need two townies to vote for him, unless Ibarra's buddy decides to bus him in search of towncred. Which is why I'm looking for additional arguments.
I'm sure you know that everyone here is aware that the fact that he has not been quick hammered does not in the slightest mean he is more likely to be scum. To even suggest it, is misleading intentional or otherwise.
