Where i come from

I was born into a bhramin family & married outside the bhramin caste. I do not fully understand or connect with this but i feel my body respond when anyone says anything derogotory. Is this really in my genes? And this I learnt while growing up that I am sensitive to my roots- just never did enough to find out ALL that I must know of them. But yet when anyone says we are 'cooks' or ' priests'... on a loose way- I feel the color drain from my face & I object instinctively. And somehow I can't forgiv. So, what is this about?
