This isn't at all an unreasonable request. Ed has brought forward a legitimate problem, and in his frustration has made a threat to temporarily ban NPOV violators. The consensus is that he should not do this, but that these NPOV violations should be brought to the attention of the community, since as Ed said, explaining NPOV and being cordial did not work.
The implication being, of course, that it is the others who violate NPOV and not Ed himself. I think it is fair and reasonable for Sheldon to defend himself and others against that claim, but so long as there are no fundamental policy questions here, the matter should be taken to the respective talk pages.
