An adjunct at FSU resigned over a face-book comment calling someone an "elitist fagoot" [sic] among other things. (The exact quote, as reported, is "“Take your Northern fagoot [sic] elitism and shove it up your ass.”]

Once again, the first amendment issue is the same whatever the content of the speech. There is no freedom unless the freedom swings every which way.
What a deeply stupid woman was doing teaching college classes in business communications is another matter. (I believe that vile freakazoid is the technical term here.) You shouldn't be punished for your obscenely uninformed opinions, expressed outside the context of your job.
There really ought be an alternative to facebook called trollbook. The trolls could just troll one another, accusing one another of being too enthralled with Obama and calling one another fagoots and kwiers. (Actually, this already exists, more or less. Some would call it "the internet." I'm suggesting organizing it better and giving everyone free reign.)
