  It is difficult to see how it could be. Although we should add two caveats. First, this doesn't rule out the existence of other separate moral objections to ‘dwarf throwing’. Second, there certainly are contexts in which this practice would constitute wrongful instrumentalisation. These may include cases in which the people thrown are substantially harmed and cases in which they do not consent or in which their consent is invalid. Indeed, this is the main point. What does all the ethical work here is context: in particular issues relating to the existence and quality of the ‘dwarf's’ consent—and perhaps also those relating to harm and welfare.
