two three four votes to re-open the question:
The question was closed as "not a real question" and currently there are
two three four votes to re-open it. From the high number of votes and extremely high number of views—momentarily, Zev's answer is at +44 +46 and the number of views approaches 2.5k—I conclude that this question is interesting to a substantial number of users of this site.
Since voting to re-open without notifying anyone is
doomed quite likely to fail, I open this thread in order to have a discussion.
I'm not particularly thrilled about this question and I suspect that the main reason for the number of views is its argumentative nature. I have to admit that I only skimmed the question and answers. I have no strong feelings about this question and I'll likely abstain myself from voting. However, I'd be strongly in favor of keeping it protected if it should be re-opened in order to
avoid try to minimize advice on saving oxygen or the like.
Added: I would be very interested in reading opinions and reasons of those who voted to re-open or think about doing it.
Edit: Now that all but one of the re-open votes have withered away, I think this case can be considered closed.
