Democratic socialism and social democracy are 2 different things. "Democratic socialism" is like "compassionate conservatism" in that its an image-driven rhetorical device used to soften the real agenda. It's still socialism, its still anti-free trade, its still government regulation and ownership (aka: domination) of all forms of commerce, its still based on the myth of a classless society, and it is still the leading ideology and means to power of the dictator. Just today,
Hugo Chavez declared himself Lord and Master of Venezuela for Everlasting Eternity, and he did so implicitly and cynically on the backs of the poor and working classes.
"Socialized democracy" is more honest, more realistic and more benevolent in its intent. It characterizes a fundamentally democratic form of government: free trade, system of checks and balances, judiciary, open society, free press, etc...and mixes in government subsidized social programs such as universal healthcare, addiction counseling, educational programs and the like.
As their names imply, social democracy is a form of democracy; democratic socialism is a form of socialism.
