Even after 500 years of muslim rule, Hindus are the majority. It's a myth propagated by some outfits that Hinduism is in danger. However, I agree with you that 200 years of British rule could change the entire administrative and educational systems in our country and also the living style of our people. To stop this, we need to educate people about the motives of some christian organizations. However, blindly saying that Hinduism is in danger would be a foolish thing.
