The Indo gov';t has a law that makes community approval a prerequisite before a house of worship can be built.
I forget the details but something like 60 signatures of church members must be submitted to local govt' as well as signatures of 100 neighbors that say that they do not object to this house of worship.
How many of the churches on the PB would be able to do this?
In a Mslm majority country this is even harder, except in cities and more tolerant areas where large numbers congregate and some level of anonymity and tolerance is fostered.
This law is applied unevenly and most mosques do not pass this law either but radical Islm groups make it a "ministry" to close churches and demand presentation of many churches "letter of permsision" and if one cannot be produced, demonstrations and threats result until the church closed. Over a 100 churches in West Java has been attacked or intimidated in some way just in the past two years.
