liberals' racism-colored glasses

Sometimes, things are really obvious, but someone needs to say them anyway. Like this comment from Ace of Spades, on Chris Matthews' observation at a Palin book signing that "they look like a white crowd to me...I think there is a tribal aspect to this thing, in other words, white vs. other people.":

Liberals are fond of claiming their thinking is more nuanced, more multidimensional, more wide-ranging, than conservatives' thinking.

So why is it at every opportunity they indulge in retarded reductivism and reduce everything to the single variable of racism?

People don't want to give up their health care? Must be racism.

People don't want to pay more in taxes? Must be racism.

People don't want to import millions of new needy poor which they are then obligated to support through social welfare? Must be racism.

Racism, racism, racism. There seem to be no other variables in this equation or inputs in this program.

(As always, be aware that the language at Ace's site tends to be a bit rough.)
