You can always predict a censorious shit-heel by how much they crow about "civility" or even more ironically "integrity." I was always told that "integrity" is a synonym for "honesty," but that is clearly not the case. No-one, and I do mean no-one who uses that word uses it to mean "honesty," though they act as if we all believe it anyway.

If you can get fired from your job for having an opinion, you must have a really fucked-up opinion. I don't need to worry about consequences because I speak with integrity and I'm not a talking scumbag. - Scott Heil (what a fitting surname for the skinhead who got me kicked off LinkedIn!)

Always remember: there is no polite way to point out that someone is a liar. Regardless of how cordial you are in your delivery, your interlocutor will always act as if you had just made an expletive about their mother. I am indeed speaking from experience.
