In princle perhaps, but in practice what happens is that particular groups of people are specifically excluded in all sorts of insidious ways. Usually they're excluded by a "homogenous" majority (homogenous relative to the aspect that defines the minority) and so there is no incentive for members of the majority to stand up for those in the minority. Examples include gays' right to marry, women's right to vote, slaves' right to freedom, etc.
