An effective argument is established by taking the time to look at both sides of an issue.
Discrediting someone's argument or learning the popular opinion is not a good way of creating arguments, while it is not very subjective to decide what is better and what is worse.

The right answer is the mandate to marry within one's tribe. Even though Nnaemeka knew that his decision to marry a woman from another tribe would upset his father, he thought that his annoyance would eventually pass away. But he had not realized that his was a decision without precedent, and this caused surprise, indignation, and sadness among his people, who, stuck to tradition, saw in Nnaemeka's act a reflection of their Lord's cautionary teachings ("Sons shall rise against their fathers") and a bad omen ("It is the beginning of the end"), hence illustrating their conviction in the mandate to marry within one's tribe.
