Yep. No system is perfect, and this one has flaws that probably allow a motivated, agenda-driven person or group to get acceptable comments removed that they don't agree with. 

I noticed yesterday, while going through the posting process, an earlier comment of mine appeared for review. A few seconds later, I got a notification that someone had just replied to the same comment. So I assume the poster flagged the comment prior to replying. If that's the case, the flagging was done just because the replier disagreed with the anti-Trump comment, which had already been adjudicated as meeting civility standards.
