Since the military defines what it means by the term, for purposes of its own rules it means what it says.
With the exception of "intends to engage in", the list all refers to overt acts. Even the "intends to engage in" term relates to a level of motivation that extends beyond mere desire, fantasy, or inclination.
A “propensity” is not an overt act, but for the record, I was directing the question to Lucky Dog, who’s been arguing against the military’s definition of the term (via analogy) with every post.
