Objectives: International law contains several provisions on the protection of family and marriage rights of a person. The concept of a "family", though not legally defined, has always been understood in a centuries-rooted way, i.e. as a union of a man and a woman. Recent decades witness aggressive promotion of distorted understanding of a family. Methods/ Statistical Analysis: The analysis of international practices as well as comparative legal instruments on human rights shows that in the 20th century the concept of a family was attacked by the lobbyists of 'LGBT's rights'. The phenomenon that was considered throughout a human history as a deviation is nowadays declared to be a universal value. Findings: The article explores the examples of France, Germany and Russia to show how protection of human dignity comes to an absurd when dignity is found in unnatural relationships and when those not willing to accept such an approach are persecuted, talking about individuals, and heavily criticized, if we speak about states. Application/Improvement: The authors of the article attempt to attract attention to inconsistencies between the obligations had undertaken by states in the domain of family rights of a person and the newest interpretations of these obligations that contract with the nature of the states' commitments.
