"obama vs. marx"

i hear people squealing about obama being a socialist---they need to read this piece and learn the difference:

The world "liberal" first used in its modern political sense in 1812, when Spaniards wrote a new constitution liberating themselves from monarchical rule. As it happens, the word "socialism" originated in roughly the same period; it came into existence to describe the utopian ideas of the British reformer Robert Owen. Such timing suggests two possibilities: Either the fates of liberalism and socialism are so interlinked that one is all but synonymous with the other--or the two are actually competitors developed to meet similar conditions, in which case victory for one marks the defeat of the other.
