If I came across a situation where the community was voting against established Meta policy (like in one of the examplesone of the examples), I would probably do similar to what the revision history states. Sit back and let the community vote. Votes are here for this purpose. With only one close and one reopen vote per person the question should settle down reasonably soon. If the community is going against meta policy, maybe it's time to revisit that policy.
I would remind everyone to be nicebe nice and if the problem continues possibly talk to said user in private emphasizing this further or seeing if there is a deeper problem (such as a user vs user dispute that expands beyond one question).
