It's impossible to eliminate hatred and negativity. But it -is- possible to foster an environment where those feelings aren't irresponsibly acted on. And that's our goal here.
And when I say "our goal," I don't mean as a site, but as each individual on this site. While I was the one who chose this objective for the community, every single person on here plays a part in it and we will obviously need everyone's cooperation in order to meet it.
I'm pretty limited on what I can do, which is why I have an amazing staff team to help me out with moderation. But our sphere of influence only goes so far, being limited to just our site and servers. Ideally, our moderators also help people resolve conflict maturely even outside of the site, be that in skype groups, league issues, etc. But, unlike handling on-site violations, they aren't the only ones who can do that.
Anyone can make a difference by encouraging and helping people handle things better. One problem, especially among the age group of people that will be in a place like this, is that we don't have the skills to know how to handle things like that well. When I say 'skill', I mean things like, impulse control, anger management, effective communication... stuff like that (not quite as fun as game-skills, though that could be an interesting concept design...). And why would we have those things? We aren't born with them. They're taught much less often than they need to be. And the lack thereof results in, as we see, strife.
If you aren't interested in dealing with others, that's okay. I don't expect everyone to, and it's important enough that as an individual you just focus on helping yourself handle difficulties better. I ask this of everyone, myself included: we all have improvements we can make, so long as we can stay open to making them. Think about what you can do to make a positive change.
