A lot of people treat internet forum threads as rooms where anyone can get onto a soapbox and shout whatever they want to, as long as it is on topic. So I see a lot of unfortunate examples where thus mistaken people waltz into a thread with a title like "I love ****" and make a post like: "I don't understand why anyone could like this SHIT, It's BORING and UGLY and SUX and the creator should be fed to the lions." What then follows is page after page of venom that linger on to poison the eyes of poor people like me who read the entire thread from start to end.
People should get it into their heads that forum threads are like conversations. Not only does it have a topic, but it's usually headed in a specific direction. If you're going to be an ass and disrupt the conversation, then no matter what happens to you as a result, you had it coming.
