Here's my very public meddling:
Dear fucknuts (I don't remember your username because I'm terrible),
I think you can do better than this. No, not better at offending people, you happen to be in the one place on the planet where friends tear each other new assholes more often than 4chan, and you don't have years of personal ammunition or any amount of emotional investment you can betray them with. You can't be better at being an asshole, but you can be better at not being one. And I think this is a good place for you to practice.
I don't know who you are, but I know some of the things you're talking about. I have so many email addresses with attendant personas that I needed to make another one just to manage them all. I've been around long enough to know that I can never be an oldfag because no one who showed up in 2008 will ever qualify. I've bounced from one community to another and I've spent so much time using fake names irl that if I ever end up in court they'll have to include it as an alias. I went into that world with a weak ego, like you did, and it caused some seriously weird mental shit. I want to unpack it, to sort it out and box it up with a pretty bow and hand it back to the internet so that other people can understand what it's like to play with that kind of identity when your brain's wired a little wrong, so people understand what they're doing before the damage is done, but it's really hard to make the words come. I think you have some of the same stuff going on. I think having a real conversation with you about all those feels would be productive, not just in making one or both of us feel better or have better footing in the world, but for us to be able to help others. I've been wanting to get this into words for a long time, but it's hard to find someone who's been through enough of the same thing to be a useful sounding board. You could be that guy.
Please don't run away just because you took a few steps backwards. You can be better than that, and I can be too.
Or kill me.
