What happened here, anyway? This started out as a collaborative writing project, an effort to build a knowledge base. It's turned into a madhouse of gamesters. Some of us still spend time editing articles or uploading images but increasing amounts of energy are going into rulemaking – worse, into untold layers of meta-rulemaking. There are debates about the legitimacy of efforts to delete proposals to control the creation of pages that govern the structure of pages that....

This is a wiki! Most editors don't seem to have any idea what kind of social structure this implies. We look to models from Real Life and apply them inappropriately here. Humans are humans and in many cases, existing political models do indeed transplant well to Wikipedia or any other large enterprise. In some cases, it's just a case of whacking a wood screw with a hammer.

Here are some points to keep in mind:

XfD processes are for carrying out policy – for implementing decisions, not for searching for consensus. There are simply far too many pages of all kinds that must pass through XfD for any one discussion to have scope beyond the single item to which it refers. Asserting global scope or introducing novel agendas is stupid. If the issue is controversial, it doesn't belong on XfD in the first place.
If you close an XfD discussion and delete the subject without an extremely large majority or clear policy in support, you're being a dick. This goes double for speedy; the least suspicion that any rational editor might oppose a deletion absolutely forbids speedy. If there's controversy over a page, there's probably controversy over some underlying issue. Wait for consensus to emerge on that before playing cowboy on XfD.
Forget trying to eliminate or discredit all the dicks on the project; kill one and two arise in his place. Do some editing. Or take a wikibreak; go fly a kite or watch some nude mudwrestling.

This is an excellent point at which to heed this last comment, put on shoes, and get out.
