While it's sad to see posts like that, I've come to terms with it: The internet gives everyone a voice... no matter how stupid.
The upside though is, that you appreciate forums like OT.com even more. I mean there are tons of civilized discussions on here... and it's not just because our collective love for Star Wars, but because Star Wars reaches back to people who are actually grown ups ;) To be fair though, I've read great posts by people in their 'teens on here as well, so it's probably just a good environment.
