I fucking well mean it.
When I write my blog posts, I'll be as mean and sarky as I desire. My targets are usually captains of industry and politicians-- if they don't have a skin that's sufficiently hardened to suffer the slings and arrows of affronts, then they need to go find other work.
But when you write a comment and you are directing it to another commenter, you are responding to someone who is probably a private citizen. That is why Rule 2.A says this, in part:
Play nice. This is my place, you do not get to shit on my floor. You are free to disagree with me and with each other, but please do it nicely. Do not use words that you would not use face-to-face. Please give each other the courtesy and respect due to a person who is armed.You feel like debating another commenter (or me), then have at it. Civil debate is not an insult contest. Do not accuse the other person of "suffering from XYZ Derangement Syndrome" or "drinking the Kool-Aid."*
If someone slips in a comment that's a personal attack on you, hold your fire. This isn't a kindergarten-- The "But he started it" defense will cut no ice here. Adult up.
I am as serious as a heart attack, people. I will enforce this.
Please do not test me.
*I thought about having a "one counterpunch" rule in that if A insults B, B gets to respond, once. And then it ends. But, nah.
