I know not all Muslims are good and not all Mughal rulers were good. There were good rulers too. We can not go back in the history and change things. We can however change things for future.
Let's go to the source, what prophet Muhammad said: "All mankind is from Adam and Eve, an Arab has no superiority over a non-Arab nor a non-Arab has any superiority over an Arab; also a white has no superiority over black nor a black has any superiority over white except by piety and good action."
This is from Prophet Muhammad's last sermon, you may read the whole sermon at: https://www.islamicity.com/mosque/lastserm.htm
