Correct, in US its a common surname, but two cultures are different. In US its also not common to compare "Smith's with "King or "Black". No one says " Blacks have started calling themselves Smiths" ?? Isnt it ?
SO YES THERE IS A BIG DEAL ABOUT IT !! INDIA IS A LAND OF CASTEISM. IF WE WANT TO ELIMINATE IT, THEN WE HAVE TO MAKE A BIG DEAL ABOUT IT
