Are you sure that most brahmins support reservations; then why are they always agitating against reservation? And FYI I have a lot of Brahmin friends and I know what they think of reservation. Give me a break.
As regards Hindus not being united, where were all the thoughts when Dalits were subjugated for 1000s of years. The foreign rulers treated Hindus as Second Class Citizens only but the upper caste Brahmins treated us worse than Animals.
