I tend to try and avoid conflict in general. That's not saying I'm good at it, or that I haven't caught myself being a passive-aggressive piece of hutt-slimed gutter trash before, but as a rule, I tend to run the other way or just stay silent than confront people about things. That said, I know I've been part of some massive drama fests in the past, and it's kinda to the point where it seems like drama is unavoidable if you want to be anything near a major player on the galactic stage. But there's also some factions and people who go about it better than others.
If I could name one thing I would blame for the site's drama, it's the "us vs them" mentalities that tend to develop, an I know I'm not guiltless. I've been in groups where they were good at saying "We're all writing together, let's have fun with it." and others who say "They're just trying to kark us, they hate us, etc." and I can say one of those is a lot more fun to write in than the other.
I think another reason is the map. Dominions are hard work, and people don't want to lose what can be hours, days, or sometimes even months of work, which makes attacks on their territory, and espically rebellions and invasions, stressful. I've said many times I didn't like how rebellions worked. I think part of that is my own neurosis, but I'd also guess part of it was that I was always on the defending side. I didn't want to lose the planets I just worked to gain. So I got upset (Probably to [member="Marcus Itera"]'s enjoyment. If so, at least someone benefited from it). As far as if we should eliminate it, I don't think that's possible. With how much of story is based on conflict, and with how much stake we tend to put in our characters, drama is inevitable. I think the best we can do is try to understand viewpoints, and remember, as Marcus said, it's a game. Enjoy it as much as you can, and try to not get too invested.
TL;DR: I avoid conflict, even if I have started Drama. Us vs Them ideas are bad. Map game can add to drama and stress.
