The author is mistaken in saying that Christians are demanding reservations. Rather, at the time of the Constituent Assembly, Christian representatives opposed job and electoral reservations but asked for the right to run their own institutions without interference.
SOme Dalit CHristians(????) are asking for reservations because they feel that they should get the same benifits as their hindu coubnterparts. I would advise them to give up CHristianity if they want to be Dalits
You cannot be a DAlit and Christian at the same time
