 Those who subscribe to the interest theory of rights can view the range of groups that might possess rights much more generously. Thus Keith Graham points out (2002, 89–93) that a group does not have to be a moral agent to be a moral patient or to be treated more or less justly or to flourish more or less well. Similarly for May (1987), McDonald (1991) and Sheehy (2006) the critical consideration is that a group can have interests as a group that are more than the aggregated interests of its individual members. That renders groups capable of being harmed or of being treated unjustly as groups and therefore suitable candidates for rights.
