Goa has a population of mix cultures: Hindu, Muslim and Christian. Expats who have made their home in Goa—mostly retirees—say that the people here are very warm and friendly. And no doubt Goa is a peaceful state, and a safe place to wander around. Even at mid-night, you can see people moving fearlessly in Goa streets. However, you must respect local cultures & customs, and shouldn’t argue strongly to anyone.
