Relevancy of a Title
Why are titles important? It is without a doubt that humans like to title everything they can think of. Such is the human spirit. I do not say this with a condescending attitude -- quite the contrary. However, personal titles are actually quite different. Titles such as Mr, Mrs, Miss, or even Dr -- relevancy of such a title only comes in to question when that particular individual argues as an opposition to someone's claim or whatever it might be that is being argued against. Think about it...when someone is making a claim that another individual agrees upon, the credentials of that person will rarely come into question. However if the opposite were to happen - such as that particular individual were to oppose the claim, their credentials would no doubt come into question.
So once again, I pose the question "Why are titles important?" Perhaps the reason for its importance only the individual would know, but it is certain that the importance of titles is quite abstract.
