There are really three ansers to that.
Most Americans value three things: The right to free speech, the right to property, and the right to freedom of religion. Communism goes against these things. In Marxist teaching, the ideal society would contain no religion, and no individual property. Thus Americans fear communism.
There are many reasons why America was so scared of Communism:
Socialism is a different kind of economy as opposed to the current system of Capitalism. In order for an entire country to change the way their economy works - it would take a monumental restructuring. Change on that level can cause massive instability within the economy, and the nation. This is one of the leading reasons the US may be scared of a Socialistic Change.
I'm not sure that "scared" is quite the right adjective, but it probably has something to do with the twin facts that a) it's traditionally associated with totalitarian governments and b) historically it hasn't worked out very well in the long term.
Probably even worse is that it would undoubtedly result in higher taxes; most Americans feel their taxes are already too high (even though by the standards of most European countries they're quite low).
Socialism was not a well-elaborated political theory at that point.
They are scared.
Many Americans feel that president Obama's health reforms smack of socialism and they don't like it.

Most Americans are misinformed on a variety of subjects, but most likely on socialism because of all the conservatives in our country. They hate the concept of socialism and misinform the public about it because they do not want it happening. Kind of like how bush brought down the world trade centers..
a state-run economy
donno
The natives were scared and th e european s were wanting them to be there slaves
That they would cause another war
he felt scared of the British for making Americans slaves.
Fascists are more prepared to build alliances with the Church, clergy, and organized religion in general than socialists are.
The others could tease Americans and make Americans scared lol
