"Brahmins were the guardians of the purity of the Vedas. So it is understandable that they would not touch those who for example remove the dead bodies of animals or clean the sewers, though a society needs people, who do these jobs, too. In the west, people also wouldn’t shake hands with them. But no issue is made out of it."
False...most people in the west shake hands with each other....they don't ask your occupation before they shake your hand
