So brahmins as a group had consciously chosen and retained many of these pointers as part of their culture and over generations these pointers as we see today are the unique tags to the genes of brahmins. Thus a vegetarian brahmin genes are fundamentally different from a non-vegetarian NB genes(even if the NB has chosen to become a vegan during his life time).
Dear Vaagmi Sir,
Just yesterday I was discussing about genes and behavioral patterns with a family member of mine but we could not come to a conclusion cos the random sampling pool of people were discussing about was just too small and a large scale study need to be done..further more environmental influence also plays a major role.
But I will have to agree with you with regards to the Brahmin vegetarian "gene" being different from a Non Brahmin vegetarian "gene".
To be specific..I choose to call it mindset but for all practical purposes here I would use the word "gene" too for discussion with you.
Ok..let me relate this story.
When I visited India as a girl aged 12..I saw a Brahmin person( he had all the identification of a Brahmin..tuft of hair..dressed as one and had a sacred thread etc).
I was at a religious place and he was walking about holding a japa mala in his hand and also a long stick on the other hand.
Then he was reciting some mantras and doing japa while walking.
Suddenly a dog ran happen to pass in front of him.
He hit the dog hard with the stick and sent the dog howling and continued his Japa.
I was shocked to see that (cos I was just a kid then..almost cried).
Ok that was my 1st experience in India.
Over the years when I stayed there as a student I realized that the average Brahmin looked down upon animals as dirty and contact with animals will render them impure and even closed their noses when a chicken walked pass them.
I realized that they are vegetarians mainly becos meat and Non veg items are considered impure and Non Sattvik and will render them impure.
Non Veg was considered non conducive for spiritual growth.
I was always under the impression that Brahmins never ate Non Veg becos out of love and compassion for animals but sadly not all Brahmins thought like this.
I was also surprised that most South Indian Brahmins loved to wear Silk Sarees.
I used to wonder when Silk is clearly Non Veg..how come they did not mind letting Non Veg drape their body?
Then when I returned to Malaysia..I happened to work as an intern under a Sri Lankan Tamilian Surgeon from here who was married to a TB lady doctor from TN India.
Once during our lunch break..this surgeon happen to notice me eating Veg food and he asked me if I was Veg.
I said yes...then he told me he is married to a TB and now his TB wife even eats Mc Donalds beef burger and loves it.
He told me if a Pure Veg TB could eat beef now..."if you hang around with me longer I could you make a NB like you start eating meat again"
To this I replied to him..."Dr..I had been Non Veg till the age of 19..I gave it up becos I had compassion for animals and did not feel right eating Non Veg anymore..hence I also do not wear silk and leather..for your wife vegetarianism could have been becos of her lifestyle...now her lifestyle has changed..so she has started eating non veg..but for me no matter how long I hang around with you..I wont eat non veg becos compassion does not change when lifestyle changes"
So you see Vaagmi sir..I do agree with you..the TB Veg gene is different from the NB Veg gene.
TB veg gene could be having a cultural component as your yourself have mentioned as a NB I can say that the NB veg gene could be having a compassion component.
