We don`t have the right to have an opinion,unless we know the answer

Well,yesterday I was talking with a friend of mine,Ruxy, and she was complaining that she had to make an essay at English with this title.I found it very interesting to discuss it,because it has all kind of interpretations.
When I first saw this title,I was thinking about this English teacher,that he`s really nuts and how the hell an Oxford graduee could invent such title to make the kids write an essay on it.After a while,I was thinking that maybe he is right..or maybe not..:-D
Usually,when we are involved in a discution with other people, we are able to create our personal opinion about that subject.We often don`t realise when we “construct” our opinion,because it is something unconscious.Everyone has a personal opinion,and its by his decision if he does or doesn`t express his opinion in public.
Many people are affraid of the answer they`ll get,so they decide to let their opinions inside themselves.Others can express their opinions just in front of a particular group of friends for example.I consider that this is a really bad thing because we live in a free world.especially a new generation full of everything “new” and I really believe that,if we will express ourselves and we`ll talk about our opinions,maybe we can manage to discover not the real answer of that particular question,but other answers that maybe are not yet discovered.
Expessing our feelings and thoughts is very important,because we have the RIGHT to express ourselves,to discover new points of view,to learn from the others.We are knowers,each and every one of us ,and sometimes,our opinions,could stand beside the real answer.
Our opinions might be the real answer of the problem or might not.Our opinions are purely subjective and they depend of the environment in which we live in.
And let`s look in the past..let`s call it…a little “history” of an answer.All kind of answers,no matter what the questions were…all kind of debates made to discover a “real” answer were made on suppositions and,of course,opinions of other people.Of course we have to have a little knowledge about that subject of discussion,but not always.As I said,we might discover answers that we never had the chance to guess them.
There`s no such thing as a “wrong” opinion.We are unique by our own thoughts and feelings,by our different points of view,and even if our opinion won`t be “the answer”,it will certaintly be an answer for other question.
From another point of view,we could say that our opinions could exist after we found the answer.Many of us,express an opinion when we have the certainty that the answer is the right one.We could say that our opinions are the “right” ones,focused on what we are looking for.But now,I`m asking you,if in this situation,are our opinions still subjective or are they influenced by the “right” answer?Where is our real contribution for solving that particular problem?
