These days there is so much of protest against derogatory remarks against race or religion.
When I was admitted to school in 1949. Right from that day I heard my classmates or schoolmates calling me 'katela' ( a derogatory term for surcumcision), 'ulta'( derogatorily referring to Urdu being written from right to left) and 'musula' ( a derogatory term for Muslims).
As a boy of six I did not understand what they meant and I am sure neither did they. They must have heard their parents say that.
"Manohar Joshi, former speaker of the Lok Sabha, a post where you must prevent the use of unparliamentary language, defended the use of the pejorative 'landya' for Muslims when he deposed as Maharashtra chief minister in front of the Srikrishna commission". This is from TOI dated 12.12.2007. You know what 'landya' means, don't you?
Among Hindus it is very common to use derogatory terms against lower castes. The parents are responsible.

May He protect both of us. May He nourish both of us. May we both acquire the capacity. May our study be brilliant. May we not argue with each other. Om peace, peace, peace.
