Scholars in diverse democratic societies have theorized tolerance in various ways. Classical liberal tolerance can best be understood as non-interference with forms of behavior or expression one finds objectionable. It has been criticized for being too permissive of hate speech and not demanding enough as a theoretical guide to civic education. Alternatively, robust respect is characterized by open-mindedness and respect for diversity. Critics have suggested that it is too relativistic and overly ambitious as a guide to civic education. Discriminating (in)tolerance suggests that tolerance should only be extended to individuals and groups who support the advancement of egalitarian politics and the interests of historically marginalized groups. It has been criticized for being overly authoritarian and dogmatic. Mutuality emphasizes reciprocity and sustained engagement across difference. Critics argue that it is not revolutionary enough to address past injustices and persistent inequality.
