If what you say about the "CAVE" types is happening here, then it could spark a "flame-war" of sorts, which would hurt the comments section.  The "Right" can give the "Left" a taste of their own medicine.  I hope Civil Comments has the budget for enough humans in the loop, to ward off such foolishness ... and that their programmer(s) can patch it away.  I really hope Civil Comments stays around, as I hate, and plan to never use any social media, especially that dangerously unsafe "Face-Book".
