As with the post just above from the person who is most negative and divisive the "system" does not seem to be able to deal with a persistent, pervasive "trawler" who is sufficiently intelligent that his/her perversity slithers under the guideline. 
Alternate, opposing views is one thing, that kind of attitude is not merely mean, it is perverse. If the "system" cannot deal with such it is only a matter of time that the site is destroyed - again. Are they even looking at this?
