Humour is located in the sensitive areas of the two basic human freedoms: the freedom of expression and the freedom of belief. The paper is focused on humour in media discourse on religion as a factor of conflict and examines important factors underexposed. According to the results of the pilot project, conducted in Russia, the approaches and attitudes towards humour as a well as a will for compromise and consensus differ in Orthodox Christian, Muslim, Jewish, Catholic and Protestant communities. Authors suggest the mapping the “zone of mutual responsibility” of journalists and religious leaders will lead to elaborating the “pact on humour” between them. For the future research authors propose to analyse the religious and ethnic factors in the formation of a sense of humour and culture of laughter in general in order to have more detailed picture on strictly religious sensitivity towards humour.
