I agree with you. I also think that religion is a delicate topic not only in Indonesia, but also around the world. We will not touch it.
But if earlier in Jakarta, you could play gambling and it was legalized, or half legalized, then why is the government of the country so categorically against the legalization of gambling?
If you make special zones on the islands, and the appropriate taxation is the same as a wonderful source of replenishment of the state budget.
It is not clear?
Regulations in Indonesia have banned gambling activities until now with illegal status, the factor is because the majority of the population is Muslim, all gambling activities are very contrary to religion and can deal with the law if someone is still determined to play gambling the police will arrest him.
Each country has different regulations so it is not appropriate to demand the same regulations for each country, for example in general about the age that is allowed to gamble at least 18 years, but there are countries that do not limit the gambling age, quoted based on information on
