I'd advise focus on Hindus visiting Dargahs like those in Ajmer , Nizamuddin , etc. Their own history books have revealed these Sufis particularly Moinuddin Chisti , were here to further Islamic conquests mass massacres loot taking women as sex slaves , children as slaves , conversion & utter destruction of Sanatan Dharma & society.
At least you won't find any of these in case Shirdi Sai Baba. Let's gather ourselves to identify & purge the true enemies within rather than expend our energies in creating fissures where none exist.
As far as other practices go I wonder how many of you've been to Shaktipeeths where alcohol and / or animal sacrifice is a must as an offering & meat is offered as prasad. Then there are places in India where the buffalo is sacrificed during Dusshera among certain Hindu communities & the consecrated meat is cooked & distributed as prasad.
These tantric / shakta practises are known as tamasic or Vamachari practises by the orthodoxy. What are we going to do with these practices assuming they interfere with one's own beliefs & modes of practice ?
