Absolutely, and the reason this does not get thrown around politically is because that is considered anti-national by us. I know people will find it difficult to understand this, but despite the issues SS gets into with certain people, SS do not see it as an anti-national act, purely a conflict of interest between brothers. I mean a common SS supporter wonders, what is anti-national if we oppose legalization of illegal shanties because the residents there will change the demography in Congress favor etc, or asking for jobs for locals when such laws already exist in other states like HP... If Maharashtrians ever perceive SS as anti-national, then SS will shut down in a day.
To put it in perspective, hardly any other big state in India has voted for a national level party as much as Maharashtra has and no other state hosts as many people from other states as Maharashtra does. I have to wonder at cheek of some people who blame Maharashtrians of regionalism. I think if we blackmail the center like say the Dravidian parties have done, then we will be considered model citizens...
