In a healthy community, in my experience: 1: someone starts a DISCUSS thread to propose adding a person.
2: if someone else had serious reservations, they state those reservations 3a: remarks from others cause the person with the reservations to withdraw them, and the group proceeds to a VOTE. 3b: remarks from the person with the reservations cause the proposer(s) to take some time to work on the issues and bring the candidate back later. In other words, the vote is more of a quorum check than a process of making a decision. This is the 90% case. It might be the 99% case. The alternative, in which a vote proceeds in spite of objections, and majority rules, is far and away the minority case. If there's such strong disagreement that you are, first of all, in this minority case, and second of all, even remotely considering the applicability of a veto to the process, I would be afraid that you've got some serious community issues and should be worrying about those.
