I for one welcome our new insect overlords the newly-clarified rules and guidelines on acceptable vs. inacceptable criticism. There's no question that passionate criticism is an essential part of comics discussion. It'd be horribly boring if we could only post things like, "I say, Eddie Tor-In-Chief of Wow Comics is a capital fellow," "Mm, quite so," and such. But just the same, if discussion after discussion consists of nothing but "Eddie Tor-In-Chief should be DISEMBOWELLED for making Testosterone Man leave the Crimepunching League, and anyone who disagrees with me is FULL OF FAIL," "Wow you're a momma's-basement-dwelling fat fucktard fanboy," "I know you are but what am I"...well, it makes people like me wonder whether they want to spend time here.
If you hate the direction a title, character or entire publisher has taken, then go for it and say so, but there's no need to get personal about it, type every other word in ALL CAPS, and generally carry on in a way that would have your boss, or a judge, send you to anger-management training if you did so in face-to-face situations.
