Wikipedia:Consensus doesn't have to change

Often, during a proposal that has been shot down in the past, someone (almost always the proponent), rebutts the reasons for denial with a simple link to Consensus can change. This may be viewed by some as dismissive, ignorant, and refusal to drop the stick. If you are planning on using this as an argument, recall the reasons why consensus was established in the first place. Maybe it was after years of discussion? Maybe there is something you failed to consider that provides a very good reason to have that particular consensus established? Of course, consensus can and does change, but it doesn't have to change.
