Personally, I wouldn't try to change the status quo. It just seems odd to me that this is OK with most people, and I'm trying to work out why it is...
Well if you get them to interact with the outside world, then you are changing the status quo.
That's what I'm saying, I'm not actually advocating that India go in and try to change their society and set up polling stations. However, my own natural inclination strikes me as odd and I'm trying to work it out through discussion.
Thing is that is a case of a group abstaining from exercising their voting rights (through isolating themselves from outsiders) rather than being denied voting rights. As such, there is no real controversy here. It would be like if the Amish decided they wanted nothing to do with the outside world & refused to vote.
