Marathas attacked and butchered Hindus as well *(see below). They raided, raped and looted Hindu monasteries like Srinegeri Shankaracharya. The myth of them as some kind of Hindu and thereby Indian nationalists is a modern invention to try and give some kind of legitimacy to the artificial construction that is the modern day Republic of India. No political entity called India has ever existed in human history, and ironically Indians including those present here are mocking Punjabis about Abdali, willfully ignoring that if their Hindu ancestors were non-Marathi, they too were probably looted, raped and massacred by their "holy" Marathas.
*"In the
Maharashtra Purana, a poem in Bengali written by Gangaram, the poet describes the destruction caused by the raiders (Marathas) in great detail:
This time none escaped,
Brahmanas, and Vaisnavas, Sannyasis, and householders,
all had the same fate, and cows were massacred along with men"
