"an idiot like the rest of us" insults me. I am one of the rest of us but prefer not to be called an idiot.
Regarding arrogance, saying your ideas are obvious (obviously true) is arrogant. Whether you intend for the statement to be arrogant is irrelevant to whether it is arrogant.
Saying things are "out of bounds" and therefore refusing to consider them is out of bounds in rational conversation.
My guess is: none of this is you communicating poorly or me misunderstanding. Rather, it's that your statements have meanings beyond the ones you had in mind while writing them.
