E/CN.4/1998/6/Add.2 page 11 Foreigners' Affairs in Berlin, of an Islamic study centre and the publication of a brochure on Islam and an inter-cultural calendar including Muslim holidays. 44. It is also essential that the media, and the popular press in particular, should cease portraying a negative image of Islam and Muslims, who are too often associated with religious extremists. 45. Religious extremism, although existing only in small minority groups in Germany, must be treated with appropriate vigilance by the authorities. The latter, like Muslim leaders, emphasized the existence of a minority extremist trend opposed to any integration within society, often using religion as a political tool, and sometimes expressing itself in a violent form within the Muslim community, such as the recent murder of an imam in Berlin because of internal conflicts. Muslim representatives stated that it was necessary to ensure proper religious leadership and that they were trying to prevent the arrival from abroad of imams who were uneducated, not to say intolerant, for example through an agreement with Turkey authorizing the sending of imams only after scrutiny of applications by Muslim leaders in Germany. 46. According to non-governmental spokesmen, Islam should be given a wider public forum and should not be confined strictly to the private domain; that could in certain circumstances promote clandestinity, which was in no one's interest. 47. Lastly, the Muslim leaders interviewed by the Special Rapporteur emphasized that they desired the integration of Muslims, but certainly not their assimilation. C. Other groups and communities in the field of religion and belief 48. During his visit, the Special Rapporteur had interviews with representatives of the Baha'is, Mormons and Jehovah's Witnesses and of the Bhagwans, Hare Krishna and the Unification Church. He also collected information on the Charismatic Christians, the Community of Universal Life, Transcendental Meditation, Fiat Lux, etc. Finally, he had consultations with associations of victims of sects, the Bundestag Study Commission on sects and psycho-groups, and the authorities. 49. In these talks, one and the same group or community might be described, depending on whom he was talking to, as a new religious movement, a religion, a sect, or alternatively a psycho-group. The Special Rapporteur wishes to point out that international law has no legal definition of the concept of religion or, consequently, of new religious movements. Similarly, the international human rights instruments do not cover the concepts of sect or psycho-group.
