Because it is the prime responsibility of abrahamics to spread their religion by any means and their religion exhorts it with the lure of a place in heaven and another with a paradise full of 72 virgins.
So i don't see how a person is happy when their primary mission is being stopped.
You cant expect only majority to be secular while the minority keep carrying on with impunity their heckling and denigration of majority and carry on their divisive agenda of trying to split India based on Religious lines.The demand for religious states has not arisen because right now they are minority,when their population rises they demand separate nation like N-E, Nagaland for Christ or renaming Kanyakumari to Kanni mary or claim Lord Balaji only owns two hills while the rest 5 hills are for church!
And it is well documented around the world how Abrahamic religions enter any nation and change the demographics and later make it a state religion with special rules.
There is a limit to tolerance too.
If history is only written by marxist muslim apologists who try to whitewash the atrocities comitted by islamic rule in India, while showing hindu rulers in bad light or even no mention of them. yes everything sounds bullshit.
