Research about red scare in 1920s, any serious problems in language?

English is my second language, and my history teacher commented my research paper that there is serious problems in language and very poor grammar.
I am so confused,because my english teacher actually likes my essay. Can anyone help me check my first paragraph to see if there is any serious problem?

The research paper is about red scare in 1920s.

The first red scare which refers to the fear of communism during 1919 to 1921 is a self-directed farce owing to the hyper patriotism and the misleading of government. The fervent patriotism and nationalism still haunted America after World War I. On the other side of earth, Russia finished the Bolsheviks Revolution and the communism overthrown the royalty with bloody murdering. Leading by A. Mitchell Palmer, the current attorney general, a campaign against communists, socialists along with aliens was launched. An alarm was spread in the country. People were arrested without warrant or evidence. Another interpretation of the red scare is the "red menace" to the American democracy.

I hope the teacher did not say it in those words. If the teacher used those words on you, you probably should not take him seriously. A good teacher does not talk that way to a student.

The first red scare, which refers to the fear of communism during 1919 to 1921, is a self-directed farce owing to the hyper-patriotism and the misleading of government. ----I added 2 commas and a hyphen. Also, this sentence says the government was being misled. I think you mean to say: ...and the misleading statements by the government.

or
...and the misleading of the people by the government.

... finished the Bolsheviks Revolution and the communism communists overthrew the royalty with bloody murdering. ---I made some small changes to verb tense.

Leading Led by A. Mitchell Palmer, the current attorney general, a campaign against communists, socialists, and aliens was launched. ---I got rid of "along with." It is not good in this sentence.

Okay friend, the verdict is in. Both teachers are right. It is great and also flawed. But you are going to be an excellent writer. I am impressed with your style.

Do not rest until you fully understand the corrections I made here. That is how to be perfect. Let me know if you have a question. Maybe I made a mistake in the way I interpreted your ideas.
