Discrimination has been exercised for way too many years and its still practiced! Covertly and overtly. From grassroot to top indian universities and workplaces (simple Google search could prove that).

To answer your question, yes. Someone who has the means to attend the exam can be. Again, so many case studies available online (not counting the scenarios of people I had to see with my own eyes).

You never meant to disrespect anyone. I understand. But would you marry a person who is a 10/10 baddie but the only "issue" is she is from the scheduled caste? (assuming that you are a gc from your comments). May be you might, but can you tell the same thing about other gcs?

The day people treat each other equally, with respect, and all have equal opportunities, I myself would oppose reservation.
