If an statement expresses someone's idea about something and does not necessarily constitute a fact then that statement is called an opinion statement. For Example: An opinion statement is "Cows are happy to give milk to humans because they look after them very well." This may or may not be true but it is obviously not a false statement. Just someone's opinion.

This is a declarative sentence. It is stating a fact or opinion about someone.
From the sentence structure of this question, it seems that you find English boring as well :)
In the sentence, "In your opinion the president was wrong about that." "that" is a pronoun. Its antecedent is presumably in a preceding sentence.
The oxymoron in the sentence is "unbiased opinion," as an opinion is inherently subjective and cannot truly be unbiased.
In my opinion, pets are a nuisance. In my opinion, trees are a good resource. In my opinion, shopping is fun!
There is no sentence in the question on which to base an opinion.
An opinion is a personal view, essentially. An example sentence would be: His opinion was pretty offensive to everyone there.
I will disprove your opinion of me.
"My opinion is that you pick up the toys if you don't want to get in trouble." or "Why do you care if I give my opinion?"
My opinion is that nikes are better than converses.
