I encounter quite often questions that are based on poor research, misunderstanding basic definitions, and likewise. In my opinion such questions should be closed rather than answered. Nevertheless, it is my policy to give people a hint or send them to a relevant text, so that they can improve their understanding. I would like to stress that I am not giving a full answer, but helping people to learn and/or ask a better question.
I am interested in opinions and practices of the other members of the community in such cases.
Remark: I am posting this as a new question, since my earlier question was closed, perhaps because of misunderstanding due to the example given in it.
