It is unavoidable that each of the major religions in Singapore will somehow intrude and affect all residents whether directly or indirectly. This is the norm here and we are all very much conditioned to the cocaphony and understand that Singapore is a secular country. When religious groups start to encreasingly deviate from the acceptable to the non-accpetable practices, then the government should step in and make known to the religious group that they are overstepping the boundary. There were many cases in the past that the government has done their utmost to request such groups to downplay their enthusiasm in their beliefs. For example, the indiscriminate burning of joss sticks and papers, not allowing mosques from using the loudspeakers and disallowing certain cults from practicing here.
I am all for the rules and guidelines imposed by the authorities, without which religious bodies will attempt to intrude the secular space of others and the fabric of our society can be torn apart. To expect the religious to be reasonable and work out a compromise between them is asking for trouble.
