It's wonderful you are so proud of being Hindu ... but do not let the pride get to your head. The 'Unfortunate Circumstances' for much of your harsh judgements is about my daughter potentially marrying another Hindu, in a country with less than 1% Hindu, where Hindu's are already struggling to survive? You showing such distaste for your fellow hindus is helping your Karma, you think? Remember Karma is both thought and action, both which must be pure, free of ego, pride, and of complete selflessness, as per Lord Krishna. I would much rather my daughter be kind, compassionate, proud Hindu with a love for the world and her fellow people, than one who is only prioritize being Brahmin while her eyes are shut to her fellow Hindu community, the world and circumstances around her. Wishing and basking in triumph that others do not reach enlightenment does not make you a good Hindu, let alone a good Brahmin.
You are nothing. None of us are. We are born, fulfill our dharma to our best extent, and then die when we are judged for the karma we have gotten. No one is talking about loosing janeau, and it is good for you you will never choose to do that -- an easy choice when the country you live in is already 70%+ Hindu country. Yes my daughter prioritizes her profession in searching for a groom. It is her form of sadhana and service to the world and community, and it is her way to filter out fellow service minded people who can accomodate her work life, goals, and principles. She believes her service to her community is through her work. You believe your service to your community is through proper marriage. It is not your place, as a mortal, to judge which is correct or better or what -- that is only up to the Gods.
You say Shankaracharya -- just one Indian Hindu philsopher, and Ramanujacharyaji -- where in Vedas Shruthi it says Varna is birth based? How about the Bhagvad Gita, Swami Vivekananda, Sri Ramakrishna, Sri Aurobindo, Arya Samaj, ISKON? Why are you selectively choosing? Remember inter-caste endogamous marriage only probably begin 100 CE -- the Vedas have existed since 1800 BCE. Varna is important for culture, social identity, status, mindset, and family health, but it is not divinely sanctioned, as per the only divine sources -- Vedas, Bhagvad Gita. the Manusmriti and Shastras, law books, even say if the rules are not relevant to not follow.
It is wonderful that Harshitaji, people like you are passionate about the community. But you are no God, no Shankarachaarya, no Lord Krishna -- just human. So please do not act like your words are the words of God, nor speak ill of my family. You do not know how Hindu we are or we are not. Do not speak of my ancestors, worry about your own.
BTW: There are many Hindu sects that believe in different ways to attain Moksha, and there are 4 ways to do it. Bhakthi, Gnana, Karma, and Raja. Marrying within varna will allow you to better practice one's dharma/karma, but is not necessary, just helpful advice. Even Adi Shakaracharya said this in his reasoning.
