Some obvious things they do:
1) use terms like fanboy or fanboi (this should be grounds for instant ban - works both ways with "fandroid" - the terms are condescending and intended to harm)
2) attitude embedded in a "different opinion" implies s/he thinks others are stupid for theirs or directly attacks others
3) their first post is negative
4) brings up Apple competitors as universally superior products (especially when it doesn't make sense in the conversation to bring up competition)
5) constant attacking of Apple and anything new or is rumoured to be coming from them - someone who's a real negative nelly without being constructive
6) threaten to leave Apple ("the magic is gone")
Differences of opinion are great, sometimes that's how we learn new things or new perspectives, but the trolling behaviours that are rife in these forums (much better than here than on other forums, not sure whether that's the overall quality of people attracted to comment here, or the moderators or both??) accomplishes one thing: it shuts down any exchange of ideas and information. Civil discourse requires that people remain civil with each other, especially when they are disagreeing with each other, or what happens is that defensiveness arises and the conversation immediately devolves into a tit-tat-tit-tat argument or all out fight.
I don't want conversations shut down, and I don't want people's differing opinions blocked - I want to talk with others about the good and bad things that are coming out of Apple (though, I have to admit, I think there's a hell of a lot more good than bad!<grin>), and I don't want a bunch of morons and idiots who's sole purpose for being here on these forums is to disrupt this (usually by intentionally starting a fight) and make me feel bad or inferior because I happen to like my Apple products.
