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:
Australia afraid of communism because the population of communism is more then Australia people
after WW1 is when most Americans were afraid it would spread to their own soil and it got worse after WW2, so some might argue it went on until the Cold War was over. some people are still scared of all types of communism today.
Americans Battling Communism was created in 1947.
Americans were very worried about the threat of Communism in the 1950s. This fear was so prevalent at the time that the 1950s are often called the time of the "Red Scare."
In part this was because of one of the main themes within the basis of communism: that communism must spread to the rest of the world. This would leave the Americans with no-one to trade with and their economy would collapse! Also (maybe more importantly?) communism opposes/condemns capitalism and America is a capitalist nation. You see the issue.
"Let the ruling classes tremble at a Communistic revolution." Because the ruling classes in America during the cold war trembled in fear of a communist revolution, and unfortunately were successfully in conditioning people into fearing and hating communism, while most Americans to this day do not even know the actual definitions of socialism, communism or Marxism.
They were afraid of the spread of communism.
Communism and the Red Scare
The north of Vietnam was the communist as the south was democratic. That is why U.S fought together with the south against the north to "Stop the spread of communism"(President Lyndon Johnson was afraid that communism will spread towards America, which is why the Americans meddled into Vietnam's business)
Many Americans worried that communism would threaten their way of life.
Because Communism removes the individual from lifes equation, and puts the states interest above any individual.
There were three main reasons that Communism was opposed. The first is that Communism creates a dictatorial system, which is a violation of the rights and freedoms that Americans treasure. The second was the Communism advocates for an end to private property and the loss of individual corporate rights for communal ownership. Americans have an almost religious fixation with the idea of private property and a strong animus against any form of collectivization, leading them to reject Communism. The third reason is that Communism is Atheistic, and so many Americans wanted to continue to have religious liberties, which Communism would not allow for.
Americans showed the fear of communism thorough the McCarthy trials. The trials tried many innocent people for fear they supported communism. Students practiced duck and cover drills in case of raids.
Americans hate Communism because during the Cold War the US made a lot of Anti-Communist propaganda.
Americans were trying to overthrow communism in Vietnam.Americans kept communism from spreading to the world.Americans surrendered them to their own devices.Vietnamese are now tired of communism because they have to share and remain equal, not grow and capitalize on their successes like America fought for and tried to free them.
That Americans know nothing about communism
Many Americans saw communism as an enemy of or threat to their country
Had to stop communism.
