Let's share the problem i faced in my life. Ones my teacher asked me, What's your name. I told him Sir, I am Krishna Kumar. He added next agge?? This is the mentality of so called upper caste. A person who is supposed to teach a student, he started theaching a student of class first by this manner. I came to my home asked my father about the same question. He was answerless, he just joked and let me moved. I could understand the reason a very long back after that incident.
Those who belong to upper caste, they never face such kind of humiliating acts in their life.
So please unless you can stop the caste system, don't ask for removing the reservation system. As this just is a counter weapon given to us.
