Wow, I step away from the forums for a day and look what trouble you get yourselves into!
This is without a doubt one of the weirder derails I've seen in a while.
As someone who has been until recently a 'raider', I see absolutely nothing offensive to raiders in anything the OP said, and I don't see any reason to think it might not be true. People randomly criticize other players' gear all the time, and on some servers it really is a favorite hobby to run around harassing soloers for their lack of leetness (so sad), so why would it seem untruthful or missing part of the story to say that somebody did something that players do with alarming frequency? And if a player wanted to start a raid v solo thread, there are so many already existing threads, and so many better ways to raise the issue than reporting that particular story.
So Happy, I'm just not understanding the basis for your claim that there is something missing here, but I think the main reason for the community's reaction is the way the message was delivered: rather than asking the OP questions that may have elicited additional information about the incident ('was that the entire conversation?' 'had you had any interactions with anyone from that kin previously?' 'have you seen that kind of behavior on your server before?' 'do you have a particular opinion on raid vs solo players that may be influencing your perspective on this interaction?'), your first words were that you did not believe what the poster was saying. You yourself in your rep thread stated that you were recently returned after a long absence, so I am thinking that maybe you have not yet experienced enough of the currently fashionable (again, sad) behavior in endgame areas to be able to understand that this type of incident really does occur often, could that be the case? And some servers have more or less of it than others, so perhaps you simply have not witnessed enough of that behavior to be able to believe that it happens, and for that I consider you very fortunate.
I also don't really understand why you would question the motives for sharing experiences on the forums. That is why forums exist. People have opinions, make suggestions, talk about what they do or do not like in the game. If I have an experience that makes me feel particularly good or bad, this is where I come to share it with other players and get their thoughts. Often the variety of perspectives that people have about my opinion will lead me to a broader understanding of the issue that will make me feel loads better about it, even if those perspectives are vastly different from my own.
So welcome back to the community, and I mean that sincerely, but please keep in mind that the gentle and inquisitive approach will often get you much farther than one that appears accusatory.
Ooh, that's a Wall of Text--I apologize, but it's been at least 12 hours since my last post so I'm feeling wordy
