although that headline might seem to be a clash between plural and singular, the subject of that title isn't plural (like more than one liberal) but the singular word 'liberals'. how does it disengage brains? i dunno. it has something to do with its use as the subject of a simple sentence.
as in 'liberals _________________________
a normal brain will then make the effort to fill in the blank with a predicate and possibly even an object. overuse of the word seems to result in an abnormality in which the brain goes totally blank and the autonomic you gotta lotta nerve system tosses in any ol nonsense that it has laying around. words like 'want' and 'iraq' and 'to' and 'be' possibly 'another' and then a real stretch: 'vietnam'.
the error is obvious to even a continually damaged, heavily abused, swiss cheeze brain. if one is going to form a sentence that begins with 'liberals' and subsequently contains the words 'vietnam' and 'iraq' , there's only one way it can be done:
liberals and others didn't want another vietnam in iraq. or anywhere else.
that's why so many of them opposed the war in iraq from the jump.
there seems to be litle chance of a cure for those who suffer from the 'liberals' brain disconnect anomaly since its victims seem unable to learn the lessons of history and are thus doomed to making the same mistakes over
and over
and over
and over.
