Good. So we are in the same page. Althought I agree with you, one must note that not ALL brahmins who are born in a Brahmanical family have bad habits like you say.
Dont you think if a person is born in a family or pure brahmins he has access to Upanishads and other Vedic scriptures much more easier than other families?
So in that sense, you must not just comment on your friends and co-worker that are born in a brahmins family but also look at brahmins in India even till date follow and observe strick Vedic rituals and penances. Just pay a visit to Kamakoti peeta (pl dont comment on Shankaracharya) and look at the brahmin children there. Their face is full of tejas and nobiolity. They are born in brahmin families too.
There are other brahmins that I personally know who are polluted with meat eating and alchohol. I was one too before I read Baghavad Gita and started living the life of a pure Brahmana.
Let us use our discrimation to separate good from evil. Not discriminate against a community or an individual based on their birth etc.
In this topic, the head Tantri is a pure Brahmana who stricly follows Vedic scriptures. He has my compelte and total support in the sense of ordering the purification jsut because he says so.
