Your thoughts are reasonable to a great extent, but for a small point
It is true, that hindus , who got converted became proud of their muslim identity later..True. but this has to do a couple of things
1.There is nothing in Hinduism that could instill a feeling of Guilt in them for being converted. Any convert from Hinduism to any other religious never carries a feeling of guilt with the, It leaves people free to choose. 2. Hinduism (in general -exceptions cud be there)do not instill fear in its followers that they feel terrible about the punishment from Hindu Gods for being converted into another religion
Due to the above two reasons the converted Hindus never felt the need to convert back
Also, the converted people were treated better by the ruling Muslim class than the Hindus who were not converted, there by increasing the stature of converted hindus in the society. Also Muslim as religion promotes extreme equality and brotherhood amongst its own members, so the converted Hindus were easily assimilated to the muslim fold.
Also the converted Hindus , were unarmed and dismantled, their movements controlled by the ruling muslim dynasties so that it was almost impossible to come out..
Also , after one or two generation under the above mentioned conditions, a normal hindu convert would have little intentions to go back to his parent religion, when the ruling class remind muslims and he getting privileges in his new found status.
