Historians, much like Journalists, have eroded themselves over the past 70 years but indulging more in ideological bunkum than what their profession entails.
It is the reason why the "Professional Historian" gets no attention at best and his jeered at, at worst.
An invasion such as Somnath is also conveniently swept under some So Mannat fairy tale. Ghaznavi destroyed it because it protected the So Mannat idol from Arabia. Lulz.
Let me know if this was found anywhere in the textbooks :
The " Padarth" of the Jagannath Puri idols was chased by Kala Pahar all the way to Lake Chilka.
In fact there are many occasions that the murtis were moved.
