Nilly, I'll Nilly the problematic posts for you. It only seems fair.
To summarize though, the problem isn't so much that he puts his foot in his mouth, or presents weak arguments, but rather, that when he is called on something or asked to clarify something (because a Buffista was kind enough to give him the benefit of the doubt), he would attack, or twist words rather than apologize and modify the problematic behaviour. He was a poster who often had interesting things to say. However, there was little-to-no respect for the fact that the Buffistas are a community with standards and an existing and pleasant culture.
Third post ever, calling Buffistas barely literate: mieskie "Firefly 2: You Can't Take the Sky From Me." Dec 19, 2002 10:23:28 am EST
Fourth post ever, dragging in Nazis and Saddam: mieskie "Firefly 2: You Can't Take the Sky From Me." Dec 19, 2002 10:46:57 am EST
The posts...
In which after a stompy had to edit other-show spoilers, he makes smart remark asking to have editors for grammar and spelling: mieskie "Firefly 2: You Can't Take the Sky From Me." Dec 23, 2002 6:43:11 pm EST
In which he says you're not trying if you're not causing trouble: mieskie "Firefly 2: You Can't Take the Sky From Me." Dec 23, 2002 7:19:27 pm EST
In which he starts tossing out the "idiot" label: mieskie "Firefly 2: You Can't Take the Sky From Me." Dec 23, 2002 9:52:52 pm EST
note: There are quite a few posts in which this continues, primarily aimed at Kristen, including posts: 1720, 1722, 1731, 1734
In which he says he didn't insult anyone, despite liberal use of the word idiot: mieskie "Firefly 2: You Can't Take the Sky From Me." Dec 23, 2002 10:12:20 pm EST
In which we receive a promise to get our pot stirred another day: mieskie "Firefly 2: You Can't Take the Sky From Me." Dec 23, 2002 10:56:25 pm EST
In which he responds to the campaigners who don't like being characterized as "rabid" and says we can call him a "rabid, raping dog": mieskie "Firefly 2: You Can't Take the Sky From Me." Dec 24, 2002 11:08:28 am EST
Note: This line continues in posts 1881 (in which he says we're all rabid because we post), 1882
In which he continues the "rabid" needle, tossing in hyper-sensitive and lacking in humor: mieskie "Firefly 2: You Can't Take the Sky From Me." Dec 24, 2002 2:24:35 pm EST
In which he gets nasty to Knut's kind attempt as playing m's behaviour as only a joke: mieskie "Firefly 2: You Can't Take the Sky From Me." Dec 24, 2002 2:43:01 pm EST
In which - after being told we can't always tell if he's joking, instead of apologizing - he again questions the sense of humor of Buffistas: mieskie "Firefly 2: You Can't Take the Sky From Me." Dec 24, 2002 2:59:37 pm EST
(actually, in the post after that, I'd thought he'd seen the light and was rooting for him, but it was a false hope)
In which he's crude about Dawn's (BtVS character) breasts: mieskie "Firefly 2: You Can't Take the Sky From Me." Dec 26, 2002 7:04:26 pm EST
In which, after it's been explained to him that we found that disturbing, he tries to spread the blame to everyone else, and attacks wolfram for no discernable reason: mieskie "Firefly 2: You Can't Take the Sky From Me." Dec 26, 2002 7:17:11 pm EST
In which he says it's all Fay's fault he's a dirty bastard: mieskie "Firefly 2: You Can't Take the Sky From Me." Dec 26, 2002 7:25:18 pm EST
In which, after a Buffista tried to explain the difference between off-color but funny posts and disturbing posts, he again takes the attack route: mieskie "Firefly 2: You Can't Take the Sky From Me." Dec 26, 2002 7:32:12 pm EST
Note: This continues in posts 2413, and is still being alluded to for the next 10 posts or so
In which he explains his attitude toward posting here and makes a "joke" that we should hurl bottles at FOX employees: mieskie "Firefly 2: You Can't Take the Sky From Me." Dec 27, 2002 3:54:25 pm EST
In which, when he is again asked to make it more clear if/when/that he's kidding, he questions the sanity of anyone who doesn't get his "humor", rather than apologize: mieskie "Firefly 2: You Can't Take the Sky From Me." Dec 27, 2002 3:57:02 pm EST
(To me, this is the one that is the epitome of the problem with this posting style. It's the post that most bothered - it showed a disregard for the community.)
In which the final "debate" started, and the problems with same have been pretty well discussed here, in natter and Firefly itself: mieskie "Firefly 2: You Can't Take the Sky From Me." Dec 31, 2002 2:56:33 pm EST
