Yes & no. I think that it can no longer be argued that S.Indians think very differently on Kashmir, it would of course differ with differing backgrounds. Secondly, unlike N.Indians, South Indians have no connection & see Pakistan as a completely foreign entity. That has over the years actually led many S.Indians to take much harder positions on Pakistan than N.Indians who would yo-yo on that. S.Indian soldiers have died over the years in conflict, whether it be in Kargil or in the Kashmir insurgency. The change has happened. Many commentators, both Pakistanis & Indians have pointed to the 1996 world cup match between Pakistan & Indian which was played in Bangalore as an example. The crowd was extremely hostile towards Pakistan & that surprised many who didn't expect such a reaction from a S.Indian crowd. Not all S.Indian reactions are the same, there is no monolithic S.Indian entity. A crowd in Chennai would likely be much less hostile than the one in Bangalore. A crowd in Punjab might be more well disposed depending on the circumstances. The psychological barrier of partition is now history, the narratives we now have does not rest on that alone.
