I'm not sure where you got that from, at all. I am talking neither about rationality nor emotion.

I am talking about "exploiting the biases of others so that they behave irrationally" -- in this example, influencing someone's decision about whether or not to do something based neither on the consequences of doing it nor their pre-existing deontological commitments, but rather on the connotations of the metaphorical language I've chosen to describe it with.

That those connotations are emotional is incidental.
