hahaha...This is so laughable. It's so absurd that you can't even reason with such perverted logic. This is from the same school of thought who say that the Jewish holocaust never existed (and believe me, there are lots of people who claim this...contrary to living and video proof).
So, there is no point in reasoning with such people. Islam was spread throughout the Indian sub continent by force and this is an undisputable fact. The muslim kings imposed Jazia is a known fact...there are so many temples in India upon which stand mosques..also an irrefutable fact (go see for yourself in Banaras, mathura)..if all these are not examples of force then I don't know what is.. It's amazing that muslims are unwilling to accept the truth about what their ancestors did...this is what makes this the most intolerant and regressive people in the world.
