Yes, and? Sure, your role is proven. But not your alignment; being voteless =/= you're town.
Flimsy logic? For the beginning of Day 2, I'd say it's fairly valid. (And trying to attack my logic? Common mafia tactic, attempting to divert attention from yourself.)
I don't know your role, so you can't really expect that to change my view.
Not really a good reason to, in any case, even with whatever else your ability is, I'm sure. I had a fluctuating vote in Skyward Sword, although it was usually a halved one. I didn't claim that, since there wasn't ever a prominent need to do so. Nor was there in this situation.
