It doesn't matter whether you are a Hindu, Muslim or a Christian ...this is something I have come to know and realise through experience and interaction. One of my close friends , a Catholic wants her son who has settled in the USA to get married to a Mangalorean Catholic and a Brahmin convert I was stumped and asked her if it is possible to know this and she said , of course the church and all of us keep a record of our ancestry. I also came to know that it s pretty much the same case with traditional Muslim families.
So, what is the whole argument about converting because of caste factors ? It just falls flat ...
Pay no mind to those who talk behind your back, it simply means that you are two steps ahead !!!
