Shoes and Civility

Does throwing your shoes at someone count as civil discourse? Does it count as discourse at all? Whether it counts as a statement or an act of violence depends on the intentions of the shoe thrower, I suppose. But can't one make a statement by means of an act of violence? So (as if a series of rhetorical questions counts as an argument) no, throwing shoes at someone is not an act of civility; but it might still be the right thing to do -- or at least not the wrong thing -- all things considered.
