The 3RR was made to avoid personal edit wars and promote community discussion. The NPOV version should stay because the majority of editors support it.
If the article is subject to POV edits you are not the only one able to revert it. If it's the reasonable thing to do, there's enough people willing to help out. All you need to do is point out the POV pushers aren't responding to a request for discussion and that their edits are indeed POV.
