When you consider the scale of wikipedia, it's easy to see why governance does not take the form of polite exchanges. There simply isn't time. You want a conversation with an admin, but that admin isn't being paid to moderate, so their time is already donated. The tedium involved with politely speaking with every abuser (and OP is most certainly an abuser) would require a full time staff. That doesn't even consider the different languages such users speak.

Wikipedia is no longer a scrappy little community of people who like writing essays. It's a walled garden of information and the only way to moderate is with an iron fist.
