You should know the difference between a Brahmin and a Priest. All Brahmins are not Priests. The humiliation you have suffered is on account of the customs practised by the Priest. I am a Brahmin and I am with you in condemning the despicable practice.
Fight. We are with you in your fight to bring such customs to their end. Do make it a fight between the sufferers and those who follow the evil customs. You should know, Brahmins as a caste do not suffer the arrogance of the kind you have charged them with.
Do curse the custom and fight against it. Do not allow it to sound like a caste war against the Brahmin. Our petty politicians do it everyday and they do get a political mileage out of it.
