Let me give you points and then we can discuss :
1. Slavery was born under British Rule, not because of democracy.
2. India doesn't have slaves, what you are referring is human trafficking which is mostly done by gangsters.
3. Govt of India doesn't force its people to work against their will, heck we have more rights than your country, you don't even know properly what happened after the panama leaks, merely stating it as a western propaganda, let alone a free media.
4. We are 1.2 billion people, each thinks in its own way to serve its country. We dont believe only a single party with only their own mindset has the right to run the country, everyone must be given a chance.
5. Unlike China, Indian army swear allegiance to the nation and its people, not to a party.
6. Unlike China, we don't use firewall to keep people in the dark and blocking magazines stating western propaganda.
7. Unlike China, Govt of India cannot even grab a land from the farmer, recent being the Singoor case.
I haven't even gone to the details of forming the government, election, and other stuff
There are lots and lots of it I can keep adding, don't take this as a way of disrespecting you or your country. You and your people do what suits best for your country, we do whats best for ours.
