This placing of Hindu kings on par with Muslim invaders in the context of iconoclasm suffers from serious shortcomings. Firstly, it lacks all sense of proportion when it tries to explain away the destruction of hundreds of thousands of Brahmanical, Buddhist and Jain temples by Islamic invaders in terms of the doubtful destruction of a few Buddhist and Jain shrines by Hindu kings. Secondly, it has yet to produce evidence that Hindus ever had a theology of iconoclasm which made this practice a permanent part of Hinduism. Isolated acts by a few fanatics whom no Hindu historian or pandit has ever admired, cannot explain away a full-fledged theology which inspired Islamic iconoclasm....

The climax was reached when the same Marxist professors started explaining away Islamic iconoclasm in terms of what they described as Hindu destruction of Buddhist and Jain places of worship. They have never been able to cite more than half-a-dozen cases of doubtful veracity. A few passages in Sanskrit literature coupled with speculations about some archaeological sites have sufficed for floating the story, sold ad nauseam in the popular press, that Hindus destroyed Buddhist and Jain temples on a large scale. Half-a-dozen have become thousands and then hundreds of thousands in the frenzied imagination suffering from a deep-seated anti-Hindu animus. ... And these “facts” have been presented with a large dose of suppressio veri suggestio falsi.... A very late Buddhist book from Sri Lanka accuses Pushyamitra Sunga, a second century B.C. king, of offering prizes to those who brought to him heads of Buddhist monks. This single reference has sufficed for presenting Pushyamitra as the harbinger of a “Brahmanical reaction” which “culminated in the age of the Guptas.” The fact that the famous Buddhist stupas and monasteries at Bharhut and Sanchi were built and thrived under the very nose of Pushyamitra is never mentioned. Nor is the fact that the Gupta kings and queens built and endowed many Buddhist monasteries at Bodh Gaya, Nalanda and Sarnath among many other places. (...)

Vibhasa, another 2nd century text, states that Pushyamitra burned Buddhist scriptures, killed Buddhist monks, and destroyed 500 monasteries in and around Kashmir. In this campaign, he was supported by yakshas, kumbhandas, and other demons. However, when he reached the Bodhi tree, the deity of that tree took the form of a beautiful woman and killed him.Shariputrapariprichha, translated into Chinese between 317 and 420 CE also mentions this legend, but this particular version is more detailed, and describes eastern India (not Kashmir) as the center of Pushyamitra's anti-Buddhist campaign.
