Of course, no one is saying that one "must" have an opinion. It is natural though, to look at something, hear something, learn something, etc. regardless of what it is, and form an opinion. There is even a humorous little quip.... "opinions are like..... everyone has one." The key is everyone has one. It is natural.... which of course might be the reason.... aaaah never mind.Quote from dbphoenix:
I've never understood why so many people believe that one must have an opinion.
Having an opinion is fine, basing a trade on it is not.
