If you’re a Westerner, you’ll eventually be faced with an option of visiting an Indonesian island (or part of one) that has adopted a Sharia-based Islamic law code. You will find little or no alcohol being served, and if you break a law, you might find yourself formally judged on Quranic principles. 

While traveling in a Sharia-based, strict Islamic area may be exotic, you really must ask yourself if it might not be better supporting the more moderate areas of Indonesia instead. There is a cultural clash in Indonesia between strict and moderate Muslims, and the moderate ones are afraid that the strict Muslims are gaining in power. They most assuredly do not want to see their entire country under the Sharia code. Consider therefore where your tourist money goes, and act according to your conscience. 

Java, for example, is moderate, and many Muslims there feel uncomfortable adopting strict Sharia laws.  Much of Sumatra, in contrast, has gone Sharia. Have a great time in Indonesia, but remember that your tourist euros and dollars do cast ballots for philosophical principles as they’re being spent.
