Never expected this from you..
Why ? Whole lot of Sultans have a recorded history of being infidel slayer and Iconoclast.
You should stand for your beliefs, if they are true. Backing down at slightest hint of resistance shows a profound lack of character.
This type of analysis are the reason that i believe that anything Left advocates should be treated a fruit of poisonous tree; evil by association.
The whole analysis hinges on a preposterous assumption that somehow Pakistan and Bengal were fringe areas of Islamic empire. This not only shows ignorance of history on part of author, but also his lack of grip on sociology and psychology.
The author conveniently forget that Pakistan and Bengal had been under Islamic rule for longest period of time than any other portion. Pakistani Punjab has seen Islamic rule for 1200 years, while in Bengal, Islamic rule has been pretty much unbroken.
In contrast to that,Islamic rule in Gangetic plains never really solidified. During sultanate era, 20 years of stable rule were followed by 20 years of Sultanate being shrinked to Delhi only.Rajputs use to go toe-to-toe with Sultans and sometime( during late sultanate, everytime) even prevailed upon them.Even Khap panchayats were able to raise an Army stronger than imperial Army during invasion of Taimur lang.During Mughal time, the very survival of Mughals depended upon co-operation of Rajputs.
This meant that political power of Islam in this area was limited by extraneous factors.
It ignores the basic Psychology of a human being. A Multani, who was living under Islamic yoke since Bin Qasim has no hope of improving his situation. He has been ruled by Muslims for as long as institutional memory of his caste goes. He had no hope. With Hindu emperors busy in fighting over Kannauj, they were not coming to his rescue. He was under unbearable burden of Jiziya, which he could discharge by becoming a muslim.
This man is more probable of becoming a muslim than someone from Gangetic plain where he was autonomous everywhere except in cities like Agra and Delhi. Where he could see hindu kingdoms just across the river and over the hill. Where ruler did not use to go full retard in fear that it would open him up for invasion or cause migration of population to his opponents kingdom ( before medical revolution, population use to be pretty low). Where he saw that Sultans self combusting after every 20-30 years
In short a Pakistani or Bangladeshi were defeated at much deeper level than military one. They had lost all hope.The very act of militaristic defiance by neighboring hindu rulers ensured that people do not lose hope and checked lunacy of Sultans.
Did this author knew the rate of Jiziya imposed on Kuffar? He probably did but ignored it in order to forward his PoV.
Jaziya was imposed at rate of 3 tola of Silver per year/per head. This is a significant amount even today, a day when silver prices have crashed due to excessive silver mining done by Spanish in Peru and Chile which caused a glut and crashed Silver prices.
