But online, everything you say lingers in the public record. Even if you delete the offending words, there's always a chance that someone got a screenshot of it. Or, you know, that it was archived in the Library of Congress. There are plenty of tales of people ruining their lives because of something they blurted out on social media. Like the woman who made a stupid racist joke, got on a plane, landed several hours later, and found out her tweet had gone viral and she was now widely hated. I'm not excusing racist jokes, but I'm a stupid guy, and know that stupid jokes pop into one's head every now and then. There's an art in not saying them, and social media doesn't exactly encourage that art.
Another weird side effect of social media is that it amplifies the importance of everything you say. What might have been funny (or at least tolerable) when taken as an off-the-cuff statement looks a lot worse if it's considered as a published statement, which is what it ultimately is. Your words are just there, hanging out, giving people time to pore over them and pick out all the meanings you never even considered.
Never say anything online without a team of PR professionals, is my main suggestion, I guess. Workshop "ass-gargler" for a few days. Let that shit simmer.
