You need to pull your member out of the shit-filled arse it is buried in before spouting blatant nonsense and falsehoods. Even in the US, the most "liberal" of places where anything goes, incest is a crime in all states except for Rhode Island and New Jersey. In these two places, incestous bastards are allowed to fuck but not marry.
In liberal Europe, the European Court of Human Rights ruled that Germany did not violate the European Convention on Human Rights when a German court convicted one sick German bastard who fucked his sister and who then had the gall to lodge a constitutional complaint that he was being discriminated against for fucking his sister after he was convicted for incest.
Closer to home in Singapore, this is the law on incest.
