My read[0] suggests it's a combination of religious, political, ethnic and economic issues, which are all inherently social things. From the causes of the splintering into 2 countries to what's happening today. And social issues crop up when the needs of some group in a society aren't being met, because they aren't being properly heard. I've seen things in the news about Modi; he doesn't sound like the type to listen to/heed anyone not in his circle.
