Thats the whole point Mr All-Green .
Even after worst kind of forced conversions ,within few generations those murky past of coertion fades away ,the neo convert behaves like the born again convert
.
They not only forget and reject their past religion, they erase the old and erect new legends to supports their wish live in comfort of denial where traces of old existence kept at bay from their new consciousness and most important factor we saw noone wish to revert back to old religion.
Anyone feeling a sense of deja vu??
I would disagree here, the Moriscos were expelled because even after a century most were Christian in name only since they were forcibly declared Christians, the reason they could not practice Islam openly was because the penalty for such an act was death and persecution.
So when you implied that if they were converted why they did not revert back, you are not taking any of the prevalent conditions into account and giving a very simplistic statement.
a) The conversion was not even an option, it was a declaration that the Muslim is now Christian.
b) Penalty for openly reverting back to Islam was most horrible torture and execution.
The spread of Islam in Subcontinent was not due to any such decree whereby the Hindus were declared Muslim one fine day and anyone going to a temple was sent to the Gallows!
That is most certainly not the case and history has not recorded any similar event as to what occurred in Spain.
Muhammad bin Qasim achieved a military objective, however he was not sent to forcibly convert Hindus to Islam.
Since there was no caste system in Islam and all Muslims enjoyed same rights, it could have been one additional factor for many Hindus of lower castes who felt the brunt of upper castes to convert to Islam and get rid of oppression.
Islam was the religion of the super power of the time and was therefore closely associated with a culture which reigned supreme in the world and very appealing from social perspective; more so to people who suffered from the unjust social segregation due to the caste system.
The mass conversion to Islam in the subcontinent took place when the pious and very humble Sufis preached to the local population and earned the respect of the locals due to the high morals and values they stood by.
The poetry of many of these Sufis is recited even by Non Muslims to this day, it was certainly not an imposed culture, it solidified its place in this region through the efforts of men of peace whose humble persona appealed to the masses.
The social system which was the hallmark of Islam in those days stood on two key principles which have always and will always be the foundation of any great society...
a) Equality
b) Justice
The fact that Islamic world has deteriorated does not mean that it was great once only through chance and military might...there were many enviable qualities in the social system implemented in the past Islamic empire.
There were many logical reasons for people to peacefully convert to Islam.
Deja Vu?
You do certainly do need that cup o coffee, there is no similarity between what happened in Spain and what happened in the Indian subcontinent.
