It is the risk that some academic communities—particularly those in the most progressive parts of the country—may attain such high levels of political homogeneity and solidarity that they undergo a phase change, taking on properties of a collective entity that are antithetical to the normal aims of a university. A collective entity mobilized for action is more likely to enforce political orthodoxy and less likely to tolerate challenges to its key ideological beliefs. Politically homogeneous communities are more susceptible to witch hunts, particularly when they feel threatened from outside.
