Spitting as I pass, as a protest???

I have had a naturally grown beard and mushtash, for the past 41 years. It's now also white, and white hair on my pate too--I do resemble Shirdi Sai Baba--to make it worse, my facial features are also identical to this not very ancient sage from India. At least 4 to 5 persons in any given day, fold their hands and bow to me--and I know, why they do so. I raise a hand to them and act as if I was blessing them , with a very serious face. Also 4 to 5 persons a day, spit at me , or spit near them ,thinking I am a Muslim gentleman--this is in Mumbai, known to be cosmopolitan. How messed up can perception and reaction be --.
