To eradicate castism---Surname or "lastname" should be at one's own will
To get rid of this problem i have some suggestions--
1)Eliminate the concept of surnames across India as it is implemented in southern states eg R Ashvin,S sreesanth,L Balaji etc..The names nowhere reflect a person's caste and discrimination can be avoided toa certain extent..Name with the Initial of father would be a possible solution
2)The other possibility I can think of is-- giving freedom to all the individuals to choose the surname of one's own choice Like xyz Indian,abc bharatiya and other possibilities one can think of..There should be local offices that help individuals to shed their existing surnames and opt for new surnames if somebody desires..Minimum paperwork and the individual would be identified with same name and a new surname ..
3) The mention of caste should not be present in school leaving certificates and other places unless the caste is of some importance for some specific reason..People can make caste certificates from their parents certificates but the mention of caste should be avoided in any document ..
India would find difficult to become Bharat unless people unite . more
