I don't have time to open up all those links, but from the sound of it, they seem to be personal defamation cases (or other edge cases like disorderly conduct in a court room; false arrests by idiotic police departments which of course do happen but generally get overturned; etc) and generally against private individuals, not politicians. OTOH, there's an established body of precedent in the U.S. (which fortunately, not too long ago, wasn't anywhere near as PC as it is now -- far from it, in fact) saying that politicians and big enough celebrities are fair game for non-specific, purely pejorative insults (like "goat fucker"), as long as they don't stray into the territory of making a specific claim of fact (e.g. "I saw the Senator drilling a away at a captive goat behind the shed the other day, and boy, you should have seen the look on his face!")
