Such qualifications of Brahmin-hood were taken to a new level when another of my other friends asked me a question ‘’Are you a Brahmin?”; I said ‘Yes’. He asked me what percentage of Brahmin I was. I was puzzled. When I asked for explanation he clarified that if I don’t drink (15%), don’t smoke (10%), don’t womanise(20%), don’t eat meat (20%), do Sandhya Vandhanam three times (15%) and don’t covet others money/property (20%) I am 100% cent percent Brahmin.
The person who assigned the marks as above, has obviously his own image of a true and complete brahmin—teatotaller, non-smoker, celibate and non-womanizer, vegetarian, performs Sandhyaavandanam 3 times daily and not coveting other's money/property. This "sample" has no relevance to the concept of brahmin contained in our revered scriptures.
87. But in order to protect this universe He, the most resplendent one, assigned separate (duties and) occupations to those who sprang from his mouth, arms, thighs, and feet.
88. To Brahmanas he assigned teaching and studying (the Veda), sacrificing for their own benefit and for others, giving and accepting (of alms).
93. As the Brahmana sprang from (Brahman's) mouth, as he was the first-born, and as he possesses the Veda, he is by right the lord of this whole creation.
96. Of created beings the most excellent are said to be those which are animated; of the animated, those which subsist by intelligence; of the intelligent, mankind; and of men, the Brahmanas;
97. Of Brahmanas, those learned (in the Veda); of the learned, those who recognise (the necessity and the manner of performing the prescribed duties); of those who possess this knowledge, those who perform them; of the performers, those who know the Brahman.
98. The very birth of a Brahmana is an eternal incarnation of the sacred law; for he is born to (fulfil) the sacred law, and becomes one with Brahman.
99. A Brahmana, coming into existence, is born as the highest on earth, the lord of all created beings, for the protection of the treasury of the law.
100. Whatever exists in the world is, the property of the Brahmana; on account of the excellence of his origin The Brahmana is, indeed, entitled to all.
101. The Brahmana eats but his own food, wears but his own apparel, bestows but his own in alms; other mortals subsist through the benevolence of the Brahmana.
102. In order to clearly settle his duties those of the other (castes) according to their order, wise Manu sprung from the Self-existent, composed these Institutes (of the sacred Law).
103. A learned Brahmana must carefully study them, and he must duly instruct his pupils in them, but nobody else (shall do it).
104. A Brahmana who studies these Institutes (and) faithfully fulfils the duties (prescribed therein), is never tainted by sins, arising from thoughts, words, or deeds.
105. He sanctifies any company (which he may enter), seven ancestors and seven descendants, and he alone deserves (to possess) this whole earth.
31. Let (the first part of) a Brahmana's name (denote something) auspicious, a Kshatriya's be connected with power, and a Vaisya's with wealth, but a Sudra's (express something) contemptible.
32. (The second part of) a Brahmana's (name) shall be (a word) implying happiness, of a Kshatriya's (a word) implying protection, of a Vaisya's (a term) expressive of thriving, and of a Sudra's (an expression) denoting service.
33. The names of women should be easy to pronounce, not imply anything dreadful, possess a plain meaning, be pleasing and auspicious, end in long vowels, and contain a word of benediction.
155. The seniority of Brahmanas is from (sacred) knowledge, that of Kshatriyas from valour, that of Vaisyas from wealth in grain (and other goods), but that of Sudras alone from age.
156. A man is not therefore (considered) venerable because his head is gray; him who, though young, has learned the Veda, the gods consider to be venerable.
157. As an elephant made of wood, as an antelope made of leather, such is an unlearned Brahmana; those three have nothing but the names (of their kind).
158. As a eunuch is unproductive with women, as a cow with a cow is unprolific, and as a gift made to an ignorant man yields no reward, even so is a Brahmana useless, who (does) not (know) the Rikas.
162. A Brahmana should always fear homage as if it were poison; and constantly desire (to suffer) scorn as (he would long for) nectar.
168. A twice-born man who, not having studied the Veda, applies himself to other (and worldly study), soon falls, even while living, to the condition of a Sudra and his descendants (after him).
The above are just a few of the requirements of a Brahmin as decreed in Manu Dharma Sastra, but there are many more. But the last one (#168) will imo, disqualify almost all the living persons (and their forefathers too) from being eligible for brahmin status.
But if we make a set of our own qualificatory conditions, then the brahmins who become so eligible, will not be True brahmins according to the Hindu scriptures. For example if we take many matrimonial ads of today boys in US/Europe, earning more than certain limit, fair, tall, etc., are considered brahmins.
