It is not the critic who counts, not the man who points out how the strong man stumbled, or where the doer of deeds could have done better. The credit belongs to the man who is actually in the arena; whose face is marred by the dust and sweat and blood; who strives valiantly; who errs and comes short again and again; who knows the great enthusiasms, the great devotions and spends himself in a worthy course; who at the best, knows in the end the triumph of high achievement, and who, at worst, if he fails, at least fails while daring greatly; so that his place shall never be with those cold and timid souls who know neither victory or defeat

Theodore Roosevelt

I think that just about summarises the credibility, or lack thereof, of your opinions. To quote another American colloquialism; "put-up or shut-up".

As always, all the best Richard

PS An English lesson: Who's means "who is", hence the apostrophe. "Whose" is the possessive form that I'm sure you meant use. Please take note

PPS If any of these words happen to be a little too long for you, you might want to try looking in a book called a "Dictionary". They really are very useful. They're only a few hundred years old, so I can understand how you might have missed their publication
