I read some of the faqs they had on their site,
about Kerry & Bush being in the same quadrant,
or complaints they got stating : "the political spectrum has moved here"
you should to.
for the 2nd one, they state that in say Nazi Germany there might have
been Nazis who weren't for some of the extreme things as other nazis
and thus make them left of other nazis. someone resisting the nazis
would be extreme. so they keep their boundaries of political-ness where
they are.
to the 1st item i mentioned, i'm not sure if they had this explanation, but
face it, the US has virtually no mainstream left. people like Kerry and Clinton
may have been somewhat liberal, but they were not leftists. they push the
corporate agenda as much as the rest of them.
but, of course, you could be right
