Re: Secular?
I’m not talking about migration during creation of Bangladesh.
Millions of Muslims from Banglsdesh cross over to India, just like illegal mexicans cross over to United States. There are estimated 20,000,000 illegal Bengali Muslims in India. They cross over to Hindu India looking for jobs. They have been sneaking in for jobs from eighties, nineties and its still going on.
Just do a simple search “Illegal bangladeshi immigrants in India”
