I would suggest NOT voting contrary to known-to-you community consensus, even if it is technically legal to do so.
Because the end result will be the same (even if you find 5 more people who agree with you that community consensus is wrong and VTC, the question WILL get reopened, either by 5 more people who agree with community consensus, or by a moderator - because typically moderator votes follow community consensus as defined by Meta).
But you will, in the process:
Create extra work for people (VTRO voters OR moderators)
Potentially create bad feelings for the OP ("why are people voting against the rules? Must be a personal attack")
Potentially create bad feelings for the community (while it is technically your right to VTC against community consensus, it does feel a bit like a mean-spirited challenge to the community, from a certain point of view - even if you didn't mean it that way)
