Not sure what you're trying to accomplish in this comment, but you're wrong anyways. This is an example of contradiction (~(P/\~P)), not excluded middle (P\/~P)..
There's really nothing to explain: You quoted a contradiction. You then typed the non sequitur "law of excluded middle"; I take it we were supposed to infer that the quote is false because of excluded middle. However, the quote is false because it is a contradiction, not because of excluded middle.
I can alter the quote so it is false because of excluded middle: > did not demand > the request is currently not "optional"
