When a group is unable to reach a consensus, group members are often accused of being stubborn, bull-headed, or unyielding. Such epithets often seem abusive, are difficult to prove, and rarely help the group reach a resolution. Those who wish to make such an accusation stick, however, should choose unyielding,  because one can always appeal to the fact that the accused has not yielded; obviously if one acknowledges that a person has not yielded, then one cannot deny that the person is unyielding, at least on this issue.
The argumentative technique employed above is conditionally advocating a tactic on the grounds that it results in an argument that would help the group to reach a consensus on the issue in question.
