I've had to repost a few as well, simply because some people disagreed with opinions in posts that were clearly civil.  I approve posts all the time that I find vehemently disagreeable, but as long as they're worded civilly I give them a Yes.

Civil Comments seemed like a decent idea at first, but it's being exposed as having fatal flaws that probably can't be fixed.  There's always going to be lots of people that get annoyed by having to screen posts they have no interest in (nor followed the context of the discussion, nor have the patience to read it all).  As such, many posts just get a default "Yes" click.  Which means even the ones that are truly uncivil are still going to make it through, just from people reposting them over and over until they find enough no-look Yes's. 

Now that people are figuring out that loophole, whatever faith there may have been in the system to weed out uncivil comments is being eroded.  Which means even fewer people will make the effort to rate fairly.
