Genocide is such a harsh word! How about nihilism?
Actually, I think we need a new word. What is a country or culture where citizens actively participate in their own eradication? Ethnoicide? Cultureicide? Balalicide? DoDoicode? Homoicide? Hatemycountryicide?
Oh, I got it:
Kapoicide: to actively participate in the annihilation of one’s people, culture, or country. See also: George Soros.
