"cough ... bullshit" is not an opinion. It's an empty exclamation devoid of any information or reasoning whatsoever. An opinion is a personal belief or judgment that is not founded on proof or certainty. There is no "belief" or "judgment" expressed in a bare reference to animal feces.
What you and other OCTabots have isn't opinion, it's
coprolalia, a brain disorder that causes "involuntary swearing or the involuntary utterance of obscene words or socially inappropriate and derogatory remarks." The root of the name of the disease comes from the Greek κόπρος meaning "feces" and λαλία meaning "babbling, meaningless talk."
But that's what OCTabots do, isn't it? Why is that? Why do references to animal waste count as either proofs or opinions among the OCTabots?
