Of course they are. The fact is bengal used to be the epicenter of Hindu civilization at one point. The issue is forced conversion by repeated Islamic hordes via invasions uprooted the communal harmony. What you have today are generation that were completely brainwashed....just look at the examples by ISIS today and apply that on a wider and more forced scale centuries ago! Remember, no UN or any type of media back then! Some Bangladeshi muslims have completely forgotten their roots.....however there are may today that do realize it and have never forgotten though their religion has changed...Kudos to them.
