If the natives of a country are an aging population, then shouldn't they reproduce with one another without being replaced by immigrants? Why is multi-culturalism pushed when the population is aging? When does genocide of a group not be considered genocide? You don't need weapons to replace a group. Out-breeding them is just as effective.

"Article II: In the present Convention, genocide means any of the following acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group, as such:

(a) Killing members of the group;
(b) Causing serious bodily or mental harm to members of the group;
(c) Deliberately inflicting on the group conditions of life calculated to bring about its physical destruction in whole or in part;
(d) Imposing measures intended to prevent births within the group;
(e) Forcibly transferring children of the group to another group.

God forbid the Koreans should want a "one-blood" race.

Today the government is scrambling to focus a sound multicultural vision for the country. How are South Koreans adapting to their rapidly changing population?
