Aceh and Indonesia is incompatible in so many aspects:
1. In Aceh, pot/marijuana is a culture; while in Indonesia, pot is outlawed
2. Indonesian Muslim is a half-assed Muslim; while in Aceh, Puritanism has a stronghold
3. Genetically, Indonesian is Malay; while Aceh has no Malay descendants at all (that's why Aceh stands for Arabic, Chinese, European, and Hindustani)
