Every time I think Wikipedia couldn't slide any further into craziness, I see something like this. Nobody ever seems to step back and ask "what exactly are we accomplishing by campaigning to get content deleted?". Somewhere between "preventing spam, vandalism, and vanity pages" and "delete everything" there's a line; the exact placement of that line seems non-obvious, but individual cases like this seem incredibly ob…
Respectfully, you don't know what you're talking about. Nothing crazy has happened here. The whole point of Wikipedia is that anyone can do stuff like "propose that WP delete a page". Note that the page hasn't been deleted yet. When Randal Schwartz is actually deleted from Wikipedia, then you have an argument.
If you'll forgive a political analogy (which seems appropriate given Wikipedia involves politics): What do Wikipedia, governments, and very young children have in common? You have to watch all of them carefully so they don't do something painfully wrong and injure themselves or others, they have a lot more energy than you do, they don't have or use much common sense, and they keep persisting because they can get away with things if you get tired and look away briefly.
And yes, I do know what I'm talking about; I've participated in Wikipedia for years, dealt with several of its policies, and watched its internal workings extensively with both fascination and disgust.
