Is this something we are supposed to accept?
Friend, empathy is a virtue. A guaranteed villager, you are not. No reasons exist for us to believe you're not an agent. If you were, well, would not this be a beautiful excuse to not speak?
"I am too much a genius, I cannot share my thoughts."
"Alright, amigo, we'll just accept this at face value and refrain from lynching, no questions asked. "
It is a responsibility of the village, to speak. If all of us took your route, no discussion would occur, and the village would shut down. Why should it be allowed of you, what we would not allow to anyone else? We have all shared our thoughts, why is it that you think yours are special, they deserve secret-keeping? Are all of us mental midgets, cowering beneath your towering intellect?
It is we who thrive on discussion; the agents thrive on silence. Those who do not speak, grant cover to the NSA agents who don't want to either. This is a position that does nothing but draw suspicion toward you - and it is well-deserved. Continue this, and I will rate you highly as a wolf. To stay silent, there is no sufficient reasoning; in this one's book, a player arguing this is either an agent attempting a stupid trick, or a useless silent villager providing them cover. Obvious lynch, either way.
