I'm from a farming family in Kerala, and I'll refute your statement. We consider ourselves as Indian as the next Punjabi or Gujarat. While the current gang of Gujjus in government are severely testing our patience at all levels, we still consider ourselves as Indian at the end of the day. Perhaps it's because most of Kerala's population is somehow associated with someone who has gone abroad, where the natives don't bother to brush them with separate strokes based on region.
haha, not even today
