This land is your protested what song?

"This Land Is Your Land" is a protest song written by Woody Guthrie in 1940 as a response to Kate Smith's recording of Irving Berlin's "God Bless America." Guthrie wrote the song as a way to express his dissatisfaction with the economic and social conditions in the United States at the time, particularly the plight of the working class and the poor. The song has become an anthem for social justice movements and is considered one of the most influential songs of the 20th century.
