Was my example not blatant enough? I really did try to choose the most obvious one I could. Let me work on another, just for you.
Whether people like to admit it or not, an opinion must be backed up with logical and coherent arguments or evidence to be correct.
This is the entire basis of critical thinking.
Your opinion on opinions is wrong.

What tastes good to you is an opinion
Musical preference is an opinion
Colour preference is an opinion
Good luck applying empiricism and critical thinking to them.
Don't remember saying it applies to all opinion. Although, you do need to be able to justify all of the above coherently all the same.
Queef you are a tool. Nihilist you wrong.
As mentioned before, an opinion on it's own is not wrong, it is an opinion. However, a LOGICAL OPINION can be wrong as the opinion is formed on the basis of logic. Therefore once the basis of logic has been established to be used then we can tag it as right or wrong. As for a standard opinion, it can be called right or wrong, good or bad, but only in YOUR OPINION. 
Working within the confines of our society, there are generally accepted facts that opinions can be compared against, and thus a conclusion of right or wrong can be arrived at in many circumstances. In my humble opinion, all opinions should be based on logic, or you should shut your mouth because you're sprouting bullshit.
I find society, religion, politics and generally all known "facts" about morals and ethics to be worthless. So the confines of our society really aren't sufficient.
But, this is how we live and we really have no choice except suicide.
Cricket is being taken over by philosophy, this is definitely too deep for this board, SHUT IT DOWN!
