People who believe cliques on internet messageboards actually exist.
Given how many people on the internet are Socially-Inept Tits (abbreviated to SIT), this happens a lot. When they encounter new messageboards, this is the typical course of events:

1. SIT logs onto a messageboard, and doesn't pay any attention to the existing contents.
2. SIT posts a new thread full of drivel which is a) incoherent, b) racist, c) a failed attempt at humour, or d) all three.
3. Regular users put their heads in their hands and get somewhat ticked off by SIT.
4. Instead of realising their mistake and backing down, SIT gets huffy and throws a tantrum.
5. SIT develops a very self-important persecution complex, and believes everyone on the messageboard (and possibly the world) has united into a group whose sole purpose is to oppress them and them alone, just like the Jews in World War II, man. The SIT will always use the word "clique" to describe this unspeakably evil group of faceless internet users.

The real-life equivalent would be going into a pub, approaching a group of strangers, talking a load of rubbish at them which is completely unrelated to their conversation, then stomping away crying about what a victim you are when they tell you to piss off. True, some messageboards are friendlier than others, but if you're completely outside the users' ken and you still manage to irritate them with your social cack-handedness, then you can be assured that the blame does not lie in the hands of a mysterious, ill-defined clique which almost certainly doesn't exist outside your oversized head.

And how, exactly is this bilge relevant to this QOTW?
Are you some kind of authority on teh interwebs or just a plain socially inept clunge (SIC)?

From what I've read of your "contributions" on this site, you are guilty of all the heinous crimes you've listed in point 2.....

Very True
As a mod on a messageboard which is dominated by quite a large aggressive clique I see this happen all the time.
