What nobody seems to have mentioned is the fact that in AfD discussions admins are *supposed* to look at all the votes and the reasonaing behind them, and make an informed decision based on that (which is exactly what several posts have said should be done). Of course there are probably a fair few who don't, and in any case the informed decision is still liable to have a bit of bias behind it, but just saying "a thousand 'delete, nn' shouldn't count as much as one 'keep, here's a bunch of references'" isn't actually adding anything to the procedure that isn't (theoretically at least) already there.
