Well, that's disappointing, to say the least.
I've been going back and forth about saying anything, because in general I just dislike stuff like this, but I was put in the camp of backstabbers personally by someone a couple weeks or so ago (have not responded because I honestly have no idea what to say to that), so...
This might come off as condescending or something, but it's the way it is. I don't understand how disagreeing with one course of action in the nearly four years that I've been posting = backstabbing, but ooookay then. I'm not in on anything that happened behind the scenes or whatever... I never am, and I prefer it that way. But my own contribution of sorts, if it can be called that, came from pure confusion, nothing else at all... Sooooo I'm a backstabber because I was confused as to what and why, in one circumstance, and as a result I disagreed with the single course of action that was being taken. Sure. I can't even care enough to be offended, just sort of... bemused. Bigger conflicts arise weekly in my group of friends, and they're not exactly... Uh, well, let's just say nobody cares at all ten minutes later.
Now, some words were spoken after I left that were not exactly kind, but A) I had nothing to do with that and did not agree with the sentiment at all (apparently, though, I did, in that world) and B) there was an apology extended.
What I do not understand at all is that these are people most of us have met in person... Gotten along with very well... Everyone had high or least neutral opinions of everybody else... I've had certain individuals that left send me PMs in the past thanking me for this or that post... How does disagreeing with one course of action in years suddenly negate all that, and transform 80% of the board into human scum? I did not think badly at all of anyone involved in that infamous GDT, regardless of what the opinions were, and I still don't, though I was personally insulted, because I'm still just confused, though now the confusion is about fifty times worse than it was initially. I just don't get the reaction at all. Maybe there was more going on behind the scenes, but... Geez, way to let your opinion of me do a 180 based on one disagreement in years, something that wasn't even personal at all.
Oh well. I really can't bring myself to care beyond being confused, as I have stated many times.

Edit:
I think the problem, maybe, might lie in the espousing of completely different value systems... and instead of having things taken at face value, intents and tones are read into them that aren't actually there because the people in question made judgments based on what they would mean if
they stated certain opinions in certain circumstances, without bothering to allow for the fact that not everyone is like them in that regard. I come up against that attitude pretty regularly irl from most people, sooo... But you just accept that people are different and take things at face value. Don't assume that they are pissed off because you are and read a matter-of-fact, straightforward post containing no insults whatsoever as a personal attack on you, because it's not, at all, and guess what? The person it's coming from might even have a high opinion of you, but you can ruin it in a heartbeat pretty easily. Don't assume that by not doing this or by doing that that the other person means the same thing you and some of your friends would. In real life, though, outside the internet, I've found that only about half of people will eventually calm down and sit and
listen to what you have to say, your explanations and what you know your motivations were, and actually believe them rather than continuing to call you a liar because you're different from them and that's just not possible. It's a sad thing, but I think that might be what's up... knowing no more about the situation than what I personally contributed.
