Apparently Big Brother is everywhere. While keeping the peace across a broad cross-section of citizens and/or website members is paramount to maintaining some semblance of civil order, it seems that there would naturally be a somewhat fuzzy line as to what shall or shall not pass with regards to posts. It is a matter of judgement but all such judgments filter through any existing biases, temperaments and or agendas (if any) of such an official. Such biases, etc. are in place and can be witnessed anywhere information is either generated or disseminated because humans are, after all, only human.
For example, one could never guess that the reporting of any given item through, say, MSNBC and Fox News even originated from the same planet except the lack of any options (that I know of). Aside from left/right slants, another method favored by those vendors charged with forming (within the populace) "correct" opinions is to take control the terms and verbage to be used or even allowed. Thus, depending upon who is talking we have such terms as "undocumented immigrants" as opposed to "illegal immigrants" as opposed to "illegal aliens" as opposed to "illegals" as opposed to "foreign invaders". Such terms all describe the same issue, however, it is only recently that increasingly more people are awakening to the fact that "foreign invaders" is perhaps the most accurate term.
