 The demand for greater inclusiveness is less categorical than the demand to eliminate discrimination. Although any environment can be made more inclusive, none can be fully inclusive for everyone (Barclay 2010, 2018). This is not necessarily because, as Barclay, following Shakespeare (2006), claims, the inclusionary features required for one impairment often conflict with those required by another. Such conflicts may be minor, temporary, and remediable. The problem is more general: 1) for many characteristics, from height to mathematical aptitude, one “size” does not fit all; 2) providing different sizes increases fit for a wider range of variation, but at increasing cost (albeit less than often assumed); and 3) it is frequently impractical, and may arguably be unjust, to ensure that everyone is equally well-or ill-fitted; it may, for example, be too expensive to ensure that left-handed or extremely tall individuals suffer no inconvenience in being statistical minorities. Full inclusion, like universal design, is an ideal—one that cannot be fully achieved, and that must be compromised in the partial satisfaction of other legitimate claims.
