If you package them in a few logical fallacies (con-artist tactics) here and there, then you're prepared to pounce on anyone intelligent enough to critique.
Not always a 'Con'. I throw out fallacies intentionally sometimes, when speaking with someone I do not know anything about, to 'gauge' their perception/capacity/vigilance/etc. Basically, just to see if they even recognize my crime. If they do, it tells me that I am dealing with someone who can take a whole other level of communication. If they do not, then I know I will need to 'tone it down' with this one.
Well stated.
