Nothing wrong with them, they are all our allies.
The problem of course is not them, it is that Hindu India cannot sustain a 30-40% composition of Muslims. As history proved, it leads to Partition.
The reason the Hindus could co-exist before, was because the nation of India did not exist until the British created it out of the many independent kingdoms of the subcontinent.
The artificial entity of India has never been able to tolerate a large proportion of Muslims. Since once it reaches 30-40%, then they will inevitably continue growing until they are the majority.
But it is inevitable.
