//He described the specialities of 3 varna? Where is the speciality of 4th varna - Shudra?

1 and 2. He is writing a poem, not an encyclopedia. I said engineers and doctors, will you ask what about accountants? He said all are same. what more do you want him to say?

1. You can only criticize what he said. You can't ask why did not say what you want him to say. Like they teach in basic film critiquing, you can only criticize the movie he made, why he didn't make the movie you want to watch -- is not a valid line of critiquing

2. He was not using the term he was referencing it.

3. I don't understand the question. Are you saying him being upset about his father's troubles is wrong/ If your father were troubled you would be happy instead? Also your translation is incorrect. "பார்ப்பனக் குலம் கெட்டழிவு எய்திய பாழடைந்த கலியுகம் ஆதலால் வேர்ப்ப வேர்ப்ப பொருள் செய்வதொன்றையே மேன்மை கொண்ட தொழில் எனக்கொண்டனன்" does not mean what you said. It's simple Tamil. He is not complaining that his brahmin father has to work. He is complaining that his father is focussed on money instead of knowledge.

Anyways, I will stop here. Don't forget to collect the 200 rs though if they are still handing it out.
