Anti-communism is opposition to communism. People began to resent communism especially after the October Revolution brought the communist Bolsheviks to power in Russia in 1917. Communism only really became relevant on a global scale towards the beginning of the cold war, since the collapse of the USSR communism hasn't been opposed as much as it was previously. People seem to think that communism is a dead ideology when in reality it isnt. We must oppose this ideology as it truly is threatening to our quality of life and the world.
