Destroying humanity as a concept?
Orange is the only option, it would encourage:
1.Sexual promiscuity. Less stable partnerships.
The more prudish females disappear, only total whores will eventually remain.
2.More sexual deviancy and lots of porn.
3.Less families and less of family bonds.
4.STDs everywhere. Public sex/porn/etc.
5.Loss of economy, science and general government control due lack of social structures.
6.Lots of rape and sexual crimes, totally unpunished.
7.humanity eventually degenerates into something like bonobo monkeys or invent AI that would rule over the resulting human zoo.
