I find it odd that people want to randomly post negative and/or obnoxious comments with no constructive purpose. It is just totally beyond me why people feel the need to do it, if someone starts raving about a band i do not like i just ignore it rather than put the boot in. if i saw that someone had started a thread on genesis i would not even read the first post, let alone dive in and start telling the world how much i hate them. First off its just plain rude, second i really do have better things to do with my time.
Constructive criticism is extremely valuable, especially if it comes from a source that is trusted and credible, but that is not what we are talking about here. if people want to be taken seriously they should make grown up comments. if you run around calling people dumbass and dullard, dont be surprised if you dont earn any respect.
I am starting to get my head around the fact that there are plenty of rude people with nothing better to do though.
