I am neither a Brahmin nor from any reserved category. My grandfather was a poor farmer. He tilled the land on the moutain slopes to increase his agricultural land. My father and uncle use to help him. My father did part time school and completed education. Me, my younger brother and 4 other cousins from our extended family worked hard to get admission in engineering, completed it, got jobs in MNCs and are doing well. From poor farmers to 6 engineers by 3rd generation. All on merit.
Our grandparents were so poor themselves that there is no question of them oppressing someelse. The reason we succeeded even in open category is that we had no choice but work hard. The muslims in the Arab world are uneducated and lazy because they have the oil to rely on. When you have to fight for survival, it brings the best in you.
I share your pain on the attrocities that Hindus might have done on your great-great grandfather. But believe me, I have nothing to do with it. Nor my grandparents as is obvious from above. The more you drag yourself to the ground, the more restrictions you put in your ability to jump. Do you know the exact conditions under which your great grand parents were converted to Christianity assuming your parents are Christians ? Maybe they were beatent to death or maybe offered a bag of rice. Since you can never know, you cannot use assumptions to fill hatred in ur heart.
I will support if you ask for free education or reservation on economic criteria for 1 gen.
