My mother is a retired teacher. One thing that she often tells is: when some of his pupils were making noise and she called one of them to be quiet, he sometimes told:
"But also Xxx was making noise!"
"Were YOU making noise? Be quiet!"

This story isn't so amazing and interesting - also because I still have problems with English language - but it's to tell that if I accuse Kissinger, your answer can't be "why don't you also accuse X and Y and Z and ... and ..." - and the same things goes for folksingers, you can't say "well, you wrote a song about Kissinger, but you didn't any about X and Y and Z".

In my point of view, so it's also a nonsense quarreling about "who is the worst s**t". I'd rather say a more poetical "A s**t is a s**t is a s**t is a s**t".

I must also remind you all that despite of its ruman rights violations China is a strong business partner for the U.S.: "business is business".

And some questions:
Which country refers to itself as "Home of the Brave, Land of the FREE?" China or U.S.?
Which country wages war everywhere in the world proclaiming itself Advocate and Defender of Human Rights? China or U.S.?
Which country has a lot of military garrisons and air bases in Italy and strongly conditioned my country's politics, both foreign and internal, during the whole Cold War? China or U.S.?

(Just the first ones that came to my mind. A lot of questions like these could be written).

PRESIDENTE SALVADOR ALLENDE:
PRESENTE AHORA Y SIEMPRE!
