I gotta remember to stay away from the "local forum" site in my local paper. Besides the fact that a lot of non-local folks are doing the commenting (and why shouldn't they?), there are so many people who have very fixed ideas about certain topics and nothing - NOTHING - will change their minds.
First, the "Christians" who hate everyone but themselves. Muslims, Jews, Buddhists, etc., all of 'em - goin' ta Hell. Christians don't propagate violence against other people, only Muslims do that. Christians are always in a defensive posture. Like, oh, Iraq.
Near the "Christian" category are the "Palinites." They are more tolerant of other religions, but negroes seem to bother them, once said negroes achieve a level of power previously thought unreachable by dark folk. All Presidents who do not perceive the value of the Divine Sarah are liklely to be Socialists or Terrorists or both. Suggesting the assassination of such a President could be classified as "blowing off a little steam."
The "Birthers." They perceive any person who won the presidency that has the temerity to be darker in hue than themselves might have stolen the election, or worse, have conspired since birth to take over the country and destroy our way of life. This Obama person has been working (along with his minions in the Communist, Socialist, and Nazi parties - AKA SEIU and ACORN) since 1962 to figure out a way to become President. Talk about ambitious.
All of these folks currently reside on the pages of various newspapers and in the news. One doesn't know their actual numbers, as reliable sources seem to have trouble counting. Unreliable sources, such as Fox News, portray their numbers as a kind of variable, with different angles of the same event showing different numbers of people. Also completely different weather patterns, and dissimilar architecture from one shot to the next. But you know, LOTS of 'em.
They also reside in their own little fantasyland, where folks like Hannity, Limbaugh, Beck, etc., reinforce their internal crazy by reiterating (for example) that people who believe the President might not be an American citizen as having "genuine concerns." I think they have "genuine concerns," too - but mostly about why their medication isn't working properly.
