Other acts of violence , such as war , torture , and ethnic cleansing not aimed at religion in particular , may nevertheless take on the qualities of religious persecution when one or more of the parties involved are characterized by religious homogeneity ; an example being when conflicting populations that belong to different ethnic groups often also belong to different religions or denominations . The difference between religious and ethnic identity might sometimes be obscure ( see Ethnoreligious ) ; cases of genocide in the 20th century can not be explained in full by citing religious differences . Still , cases such as the Greek genocide , the Armenian Genocide , and the Assyrian Genocide are sometimes seen as religious persecution and blur the lines between ethnic and religious violence
