Sorry, Scoop, but Genocide has to at least include killing, because that's what the "-cide" means. Some have referred to "cultural genocide," but that term is contemptible. It's like calling a fantasy about consentual sex, "mental rape": It demeans the horror of the actual term.
By your definition of genocide, almost any societal change can be termed genocide.
Neither Raphael Remkin, who coined the term, nor the Government of the United States, a signatory of the Genocide Treaty, would agree you. Accuse them of fantasies and demeaning genocide, not me.
Raphael Lemkin, the inventor of the term genocide
Generally speaking, genocide does not necessarily mean the immediate destruction of a nation, except when accomplished by mass killings of all members of a nation. It is intended rather to signify a coordinated plan of different actions aiming at the destruction of essential foundations of the life of national groups, with the aim of annihilating the groups themselves. The objectives of such a plan would be the disintegration of the political and social institutions, of culture, language, national feelings, religion, and the economic existence of national groups, and the destruction of the personal security, liberty, health, dignity, and even the lives of the individuals belonging to such groups.
Raphael Lemkin, Axis Rule in Occupied Europe (Wash., D.C.: Carnegie Endowment for International Peace, 1944), p. 79.The crime of genocide involves a wide range of actions, including not only deprivation of life but also the prevention of life (abortions, sterilizations) and also devices considerably endangering life and health (artificial death in special camps, deliberate separation of families for depopulation purposes and so forth). All these actions are subordinated to the criminal intent to destroy or to cripple permanently a human group. The acts are directed against groups, as such, and individuals are selected for destruction only because they belong to these groups. In view of such a phenomenon the terms previously used to describe an attack upon nationhood were not adequate. Mass murder or extermination wouldn't apply in the case of sterilization because the victims not murdered, rather a people was killed through delayed action by stopping propagation. Moreover mass murder does not convey the specific losses to civilization in the form of the cultural contributions which can be made only by groups of people united through national, racial or cultural characteristics.
