If you are a born christian, why were you named Ashish ?
American history is not christian history. Red Indians were not christians (remember tribals ). Of course, they were decimated and converted.
Yes, now majority is christians in America. But, why dont you try and say in public it is a christian nation ? I guess you might be slapped a lawsuit.
If you are brown skinned christian, most likely a white bigot will not know you are a christian, than you will have to go explaining the whole nine yards.
About us Hindus, I personally know of none who have their name changed. All their kids have nice Hindi/Sanskrit names. But, yeah, as I said, there are definitely few black sheep everywhere.
