[Invincibly Ignorant]

Actually, that was not an opinion. It was an instruction. Is English your native language? Here's an instruction for you: Come back from leftist slander land, and try not to bear false witness against your neighbor.

Oh shucks we have disagreement. Imagine the odds. I believe it was very much an opinion.

[ArrogantBustard]

Your homework is to look in a dictionary for the words "opinion" and "instruction".

See which one better fits a sentence, such as "Come back from that place", which is made in the imperative.
