Q 1. jahangir may had killed bikramjit's son(wether correct or not) but it has nothing to do with islam as it is political move, whoever king won the battle he has taken hard steps with his enemy wether it is muslim or pre islamic hindu kings(recent example is execution of saddam by US)
Q 2. why u r condemning ashoka, instead he had united india, yes all other hindu kings were fighting & all bad practices r happening in ur religion at that time. Ghouri was helped by jaidev against prithviraj chauhan, babar was called by rana sanga against ibrahim lodi.
Q 3. conversion was not forceful it was dalit hindus who converted due to attrocities against them, even if today also this conversion is taking place eg; lot many(10000) approx. dalits converted to buddhism recently on ambedkar jayanti in maharashtra
to sum up u simply cant digest that muslims has ruled this country, they mixed up here, changed the culture of country, u ppl consider muslims as invaders without knowing that u r also invaders( aryans). this country actually belong to nomadic dravidians who has been barbarically treated by aryans some 3000-4000 yrs ago
