You'll do well to read some history and realize that Sati as a practice is no more prevalent in India except for one or two remote cases. Coming to Kamasutra, it is the crown piece of all that Indian culture has to offer to the world - the art of making love. We dont resent Kamasutra. We are very proud of it.
As far as our religion is concerned, we are very well aware of our religion and we understand it. Anyway, that is completely irrelevant to the topic at hand and the points raised by the commenters. If there's anything wrong with our religion, it doesnt automatically make other religions good or better off.
You are nobody to ask us to shut our mouth. We enjoy the right to express, unlike in the country from which you are (maybe Pakistan) and we are proud of it.
