This is a perfect example of how the internet is a curse as well. The world has always been choked full of stupid. It has always existed and the uneducated, misplaced, ill-advised, and even inflammatory statements are a byproduct of said stupid. Everyone is capable of it. I've had my moments and likely so have you all. Once upon a time, it faded into obscurity after only having encountered a handful of people. I look back at my younger, less tempered years and I have had more than my fair share of those moments.
Now, those moments are public and permanent. They are burned onto the internet while the author is shrouded in a warm, safe blanket of anonymity. These stupid statements and ideas are thrown out into the world to be permanently archived for the entire world to see.... forever. Over the weeks and months after these moments are posted, everyone has the chance to see and comment. So instead of some random statement made in front of a person or two, it becomes visible to thousands or more. Instead of a verbal hiccup, destined to fade as quickly as it was said, it is stamped into the minds of everyone it touches in it's now permanent lifespan.
One of the reasons I like this forum, is that it tends to be populated by adults. Not all of us are of course. Even more of us revel in our immaturity from time to time (the shitpost meter is off the charts here). For the most part though, this is a very mature forum. A lot of thought has gone into some of the more serious topics and the discussions here are thought provoking at times. These forums are not the norm though.
Just imagine if you found out that the poster on the ED forums was a 13yo. It's entirely possible. What if they were piss drunk at the time. What if they had mascara running down their face while they listened to "Vindicated" by Dashboard Confessional. What if they actually owned a pair of jnco pants. What if they were just trolling. Would it change your opinion? Would you be able to take the post as seriously?
That's the curse of the internet. Anyone at any time and under any circumstance can post up anything. It sticks like a fly to a windshield every time, for better or worse. Once it's there, the world can review it and interpret it however they feel. It can empower more stupid to stand up and agree just as easily as it can provoke deep and changing thought.
