The problem with that argument is that it assumes your presence will help to build an encyclopedia, and there are quite a few people who feel your past behavior has hindered the building of it, wasted their time, or will be a distraction to them and others on here if you are back.  Just because it's the encyclopedia that anyone can edit, doesn't mean it is the encyclopedia that everyone should edit.  That idea seems to be lost on some critics, that there is no "right to edit Wikipedia".  David ''''''
