What god gets happy when some 50 men including four frenzied drummers keep an entire neighbourhood awake for over 3 hours in the dead of the night?

In the last three years that we have lived here, we have had several godly processions disturbing general peace. But this was the last straw. The procession started at 11 in the night from somewhere in the labyrinth beyond. The noise took an hour to die out of our range of hearing. At midnight, when things had quietened down, we stumbled bleary eyed to bed. Only to be rudely woken up again at 1 am. It soon peaked, as the return journey closed in on us. And stayed at that peak, right below our window, for a good 15 minutes. And so the procession proceeded, painfully slow, stopping every 100 metres or so and going into frenzies. We even called the cops, and said how can you allow such public nuisance at this time of the night? But it's god's business, they said.

If that particular god was really happy yesterday, I really don't want to know that god.
And if your religious sentiments have been hurt by this post, please explain to me this style of worship and why it is unavoidable.
