Many critics of the term argue that the demographic divisions (racial groups, whole religions) the term attempts to insulate from group criticism are arbitrarily or ideologically selected. For example, why aren’t lesser political groups (atheist organizations, for example) or smaller religious denominations (scientologists, for example) equally protected by the label and the stigma surrounding it? Thus, instead of protecting the powerless, the term seems to insulate from criticism those populations with sufficient numbers, power and prominence to command protection. After all, any number of randomly selected demographic categories could be deemed above group criticism or political opposition, yet few are. Why do certain groups seem to be so much more worthy of the term’s protections? In sum, the term appears to place arbitrary or ideology-laden restrictions on speech and activism, in defiance of the liberal democratic tradition, which asserts that all ideologies, movements, groups, and religions are fair game for philosophical critique and peaceful opposition.
