Rather than looking at the two back to back, and letting the abject fear of the word "USSR" and "Communism" make your argument, Why don't you tell me what you disagree with in FDR's Progressive Doctrine, and why?
Its veers from the constitution in such a way that puts decision making power into the hands of government that We The People are guaranteed to have for ourselves.
Who gets to decide what is adequate food?
Who decides what is adequate cloathing?
Who decides what is adequate housing?
Does the farmers right to sell his food at a rate that earns him "a decent living" conflict with my right for adequate food? who decides this?
Who decides what is a decent home, does everyone get the same exact home as me? If not why do they get better/worse homes with the same size family?
Who decides what level of health care is adequate for me?
I tell you I'd like to make those decisions for myself. The government has no constiutional authority to make these decisions for individuals, if it did FDR would not have needed to write a second bill of rights. There was a reason the founders didn't include these powers within our government, because they belong in the hands of the people not some washington fat cat beurocrats.
People have already mentioned that FDR used a belief system that was not in conflict with the Constitution. So I will not add on here. I would like to remind you that the USSR had a constitution of sorts that guaranteed many things they never delivered on.
Comparing the USSR and American leaders is comparing Apples + Oranges...both fruit, yet different in ways you fail to grasp or choose to ignore. Either way you end up looking like a fool.
Actually there IS a valid comparison between the USSR and America...
Lenin is to Stalin as Reagan is to Bush...
Socialism is liberal. More people (preferably everyone) have some say in how the economy works. Democracy is liberal. More people (preferably everyone) have some say in how the government works. "Democracy," said Marx, "is the road to socialism." He was wrong about how economics and politics interact, but he did see their similar underpinnings.
Communism is conservative. Fewer and fewer people (preferably just the Party Secretary) have any say in how the economy works. Republicans are conservative. Fewer and fewer people (preferably just people controlling the Party figurehead) have any say in how the government works. The conservatives in the US are in the same position as the communists in the 30s, and for the same reason: Their revolutions failed spectacularly but they refuse to admit what went wrong.
A common mistake is to confuse Socialism, the economic system, with Communism, the political system. Communists are "socialist" in the same way that Republicans are "compassionate conservatives". That is, they give lip service to ideals they have no intention of practicing.
Communism, or "scientific socialism", has very little to do with Marx. Communism was originally envisioned by Marx and Engels as the last stages of their socialist revolution. "The meaning of the word communism shifted after 1917, when Vladimir Lenin and his Bolshevik Party seized power in Russia. The Bolsheviks changed their name to the Communist Party and installed a repressive, single-party regime devoted to the implementation of socialist policies." Those socialist policies were never implemented.
"Stalinism is a state in which exploitation is controlled by a ruling caste.... at the expense of the working class." This is the exact opposite of what Marx and Engels were trying to accomplish, and is precisely what George W. Bush and the Republicans are working so hard for.
Most of the Republicans/conservatives/dittoheads I know are basically good people, but they're gullible fools who have spent more than 20 years burying themselves in lies needed to resolve the cognitive dissonance created by Reagan's betrayal. Reagan called the Soviet Union an "evil empire", but as we've seen it wasn't much of an empire and most of the people in it aren't particularly evil. Khrushchev repudiated Stalin after he died in 1953, but wasn't strong enough to change the system or the cult worship that kept the dictatorship alive.
Republicans need to repudiate Reagan, but there is no one out there who has the guts to tell the truth. The GOP is reduced to whining, flag-waving and outright lying. The shame of being a conservative has never been greater.
