Food and drink are one's personal habits. I would never comment on anyone's habits.
If I was given Chicken and meat in my very young age then I would have been eating those creatures but I was born in a Jain Family where I was given Fruits and Vegetables to eat so here I am.
By drinking alcohol and eating meat does not make you a better person.
Since I have come to this country I have never lost my individuality and I am still the same.
