Just because you are a product of Lalitpur Mental Hospital you think you know everyone else who went to Lalitpur Mental Hospital. Haha your pea size brain is not able to think anything bigger than your inferiority complex lets you. Who thinks of upper caste and lower caste in this day and age specially when living in America.

Your existence obviously is fueled by your inferiority complex most likely due to your lower class upbringing as you have implied. I eat equally from the plates of vaishya, sudra, untouchabl,e bahun, karki, damai sarki, I don't discriminate and my caste means nothing.

You are stuck in that ancient stupidity and you think you know more than everyone else. But you know something? I feel sorry for you and hope you can come out of your less than mediocre existence by understanding and appreciating this world a little better than you currently do.

Take it easy mate.
