C'mon, Be Nice To Each Other.

And here, I vent.
I like online communities. I have participated in numerous forums on numerous topics and generally there are no problems. It's fun in a way, to say what you think, to answer questions or to ask questions of your own with the possibility of communicating with people from all walks of life that you might never otherwise have the opportunity to interact with. And yet, there are some people I have encountered over the years of exploring topical message boards, chat rooms and forums who cannot engage with these forms of communication without being complete and utter pricks. And these forum nazis are becoming the norm. Example: without using any names, there is a forum that I have had dealings with on a particular topic of popular culture. There is one individual who makes seemingly a million posts a day on whatever topic, whether his comments are relevant or not to the questions or whatever. And each time, he shoots people down and basically comes across as an arrogant fuck - so so much better than everyone else because he has his own website, because he has published books (apparently). My question is, if he is so amazingly worldly and knowledgeable, why does he spend all day responding to posts on an online forum, pissing people off? If you need more, go and read some of the user comments from urbandictionary.com. People are getting seriously slagged, really really cruel comments are made just because someone makes an addition to what is a ridiculous yet humorous web site meant for nothing more than fun. So why must people get so freakin' nasty? Do they talk like this to all people they encounter, or just those who can't directly slap them in the face for being such total assholes.
I am not a person who can say that you shouldn't say nasty things to or about people. I say nasty, judgemental things all the time, and think them, sometimes dream them. But not everything that comes out of my mouth or keyboard is a slag off. So, here's my gripe, enough is enough people. Before you write something fuckish towards someone (yes, I have just decided that fuckish is a word now. I'd put it on urbandictionary.com but for fear of someone responding fuckishly to my contribution), think, would I say this out loud to a real person.
