Opinions...

It was recently mentioned to me by a good friend of mine that "All writing is opinion."

I don't fully agree with this, but then that's just my opinion.

We all know what opinions are like. So then everyone has one, and everyone is entitled to one. Which reminds me of the case against vanity publishing, wherein people will freely publish what they want and there won't be any filter of quality. Who's to say that my opinion is better than yours, however researched and polished it may be? It's yours, because the events in your life have moulded it to be so. A person's opinions could be said to play an integral part in who they are, and why should someone's identity (and stability as a result) be compromised to adopt an opinion which will force them to re-think and take steps backwards?

These are all questions I have as well.

Literature wholly comprised of opinion is a disturbing thought to me. What about the stories which were meant to function solely as stories without morals or what the author thinks? Is that possible?

If the question is what kind of literature do I value, that which is rebellious and subversive or that which isn't challenging and depicts common everyday aspects of life in clever and poignant ways which I previously haven't thought of...the answer would be both.
Both can be based on opinion and both can allow readers to glean their own meanings from the texts. But would they be better without?

Throughout this post I've gotten very tired of discussing something which has no answer and only leads to more dead-end questions. Which I suppose is the apotheosis of bad writing. So it would be best to stop now...
