So, in "real life", we tend to automatically calibrate our response to somebody saying "I don't like that", depending on how often we've heard the same person say they don't like stuff. If they say it a lot, we don't give it much weight. If they rarely if ever say it, we give it more weight. Also, if two or three other people have already told someone (in "real life") that they don't like something, we tend to regard somebody else who jumps in to say it, negatively. It seems not too hard to implement on SO that downvoting a question that is already negative, should either be disabled or else weighted less. Lastly, in "real life" we are more tolerant of piling on, when the same person has been given modest negative feedback before, and keeps doing it. If a person has several questions with negative score, it might make sense to allow more downvotes. For example, with only one question with negative score (e.g. a newbie), it cannot go below -1. If you have two questions with negative score, it can go to -2, etc. All seems totally doable, but everything turns out to be more complicated than it looks from the outside, so I suppose they have reasons for not doing it.
