In Shakti/Devi tradition Meat isn't something of a sin but is consumed, Shakti Tradition is followed a lot in Bengal area, they eat meat in Durga Pooja too. Nearly all Bengalis including Brahmins are non veg. So this decision doesn't makes sense by that point of view but I think it's not something of a big issue.
Btw don't you think if non veg is banned here, we should ban Garlic/Onion in Train's foods that are going to Jain sites and provide Halal food in trains that are going to places like Ajmer?
