Doug, a "straw man" in standard usage, is an supposed argument, opinion, or statement of claimed fact mentioned solely because it is easy to shoot down -- which the person mentioning it proceeds to do.
A "straw man" is advanced without regard to whether the "other side" made that arguement, stated that opinion, or claimed that fact because, again, the objective is to have an argument to crush.
Example: "If we had staked our national existence on Lyndon Johnson's naive and crazy trust of the Commies, we would all be dead or enslaved." [But he didn't.]
Example: "Someone called call Master Ki a crook? He is as honest as the day is long" (testimonials of honesty follow.) [But no one did call him dishonest or a crook.]
Example: "Someone said that Master Ki makes inferior knives? The quality of his knives is of the highest" (testimonials of quality of knives follow.) [But no one did attack the quality of his knives.]
"Straw men" arguments often rely on the "Dopeler Effect": the faster a stream of irrational arguments is directed at the listener(s), the more likely they will be mistaken for rationality. Politicians are especially good at this tactic.
The expression does not, in any way refer to ANY person, living, dead, or other.
("The Strawman" might be taken to refer to a character in the Wizard of OZ, which is somewhat OT.)
In the alternative, the crediting of fictional attacks on Mr. Ki may result from one imagining that anyone who is his "enemy" must surely be saying those things. So a rumor to that effect that a mythical attack has been made is accepted, and reacted to, with no effort at confirmation. The rumor fits the preconception.
