Shared superordinate identity is neither necessary nor sufficient for intergroup tolerance

Evidence

It might be argued that such a resolution is easier to achieve in the international case because, according to the ingroup projection model of Mummendey and Wenzel (1999), it is easier for competing groups to be tolerant of each other if they do not share a superordinate identity. This is an interesting idea but it should not be adopted uncritically. As McGarty (1999, in press) argues, the idea that self or other categories have the sort of hierarchical organization that is assumed by self-categorization theory is questionable. Be that as it may, there is plenty of evidence of intolerance and hostility toward outgroups by ingroups that do not share any obvious superordinate identity. Indeed the assertion that some other group is subhuman is customarily invoked in justifying genocide. — Nyla R. Branscombe and Bertjan Doosje (eds.), Collective Guilt, 800
