You and many like yourself suffer from inferiority complex brother!
You are still welcome into the folds of Hinduism! What ever way you pray remember you shall always be termed by Outsiders like Chinese Japanese, Arabs, Italians as an Indian and not as a Christian!
You can't change your Indian genes!
You may have suffered torture from few upper class Hindus. But your Identity is always Indian--that you cannot change!
By the way why not one Indian Christian has become a Pope?
There are thousands of such questions. So from the frying pan into the fire- such is your fate.
Conversion is a political tool,it has nothing to do with God!
Remember Saint Chokhoba of Maharashtra and Saint Kanakdas of Karnataka did not undergo conversion. Their hymns are sung in schools and colleges do post graduate thesis on them!
