If there are any number of History books to prove your point (..that Muslim Rulers converted by force, or discriminated Hindus) then you shuld come handy with BEST of the References.
In my life I have been investigating on such references. This is my finding:
1. Either they do not exist outside Rightwing Propaganda Sites
2. They are circlar references (a siting b as refernce, while b sites a as reference)
3. They have been badly distorted out of context (example Auangzeb dealing with Panjab rebellion by Sikhs).
So my opinion based on research is that communal masaala available on Rightwing Propagandists Websites is just a Bunch of LIES aimed at spreading hatred against Islam
