Your assessment is correct. The Civil Bot  "tests" us on how we "vote" ( which you have to do in order to get your comment posted)  NOT on the content of what we write. It is to "teach us" like Pavlov's dog, when to press the button and if we hit the wrong button we get the "black flash".  If you have lived in Alaska or the parts of Alaska where loggers and fisherman live, your tolerance for certain words becomes a matter of everyday language. If you believe in true freedom of speech, you will allow those who you don't agree with the same opportunity to be heard as you get. 
Freedom of speech allows people to be honest about what they believe in or what they have to say regarding what other people say.
Once you take it away, or limit it, people make the mistake thinking everyone thinks and feels the way they do. 
I believe there are certain folks or at least one who has managed to figure out how to get comments he disagrees with taken off. He has many aliases, pushes a political agenda
