I would say calm down, no one here is disagreeing with you, or with the history or the geography of India, nor is anyone here claiming the opposite of any of those things that you are worked up about.

You probably read too much into cstross's comments, maybe you didn't, but your comment reads like you are very angry about what he said and are admonishing him/us for getting India's history wrong and giving us a history lesson.
