Maybe they are out of topic to argue with? Banning Bitcoin seems very ineffective and pointless as anyone can access it with just an internet connection and a computer or smart phone. Not to mention Virtual Private Networks which comes very hand whenever websites relating to bitcoin market is blocked. Better accept it and let the entire citizen of India get informed of Bitcoin before the entire world starts to use it. I know a lot of smart people in India and they are very hard working so they should not just ban it instead support Indian developers relating to blockchains and bitcoin.
