Going overseas into large cities apartheid was a evident as the nose on my face, people segregated naturally toward their own communities, religions. Simply not labelled or done as happened here.
Irony is even within countries with one colour, one religion, division occurred only outlawed within the country itself in 2013. Noted living in Durban although not as prevalent perhaps within our Indian population I did encounter a few.
These four castes are the Brahmins (priests, teachers), Kshatriyas (rulers, warriors), Vaishyas (landowners, merchants) and Sudras (servants), and the 5th group is the group of the untouchables, called Dalits.
All humans are equal at birth, all humans are divided of their own doing, is the conclusion I have reached. Rich/Poor, Religions, Colour makes no difference it's divided, so stupid!
