it's not so much a "duty,"
All of:
- the statement in the posted article
- my question about that statement
- the response to my question
- my response which you originally replied to
- my question, which you quoted in the comment I'm replying to here
were about duty.
Whatever you're talking about, it isn't an answer to any of my questions because you're not talking about duty.
You seem to be a bit off on one. Your analogy doesn't make sense. Someone posted an opinion article which contained a statement that I questioned. Other people responded to my questioning. Discussion ensued. Seems pretty normal and expected to me. It seems like the misunderstanding is on your part.
