on serious note
I am sure Mughals did desecrate some old Hindu holy places. so you never know
these kings were usurpers and they OWNed the land and the people and did what pleased them. even going as far as making a new religion to suit themselves or .. have their infant or toddler brothers executed to ensure firm grip on the crown once their father died.
apart from some monuments, palaces and tombs in their names I am hard pressed to see any library, school, discovery center any public service place like hospital etc at the level of say Red fort, or Badshahi Mosque or say Taj Mahal
but then again a counter argument might be, what Grand public service monuments did the Hindu and Sikh Maharajs built apart from the places of worship for their selected Deities?
