Generally speaking, "right" refers to the thought and behavior that lags behind the reality, can't advance with the changed situation, and attempts to go back in time. Politically, they are often reactionary, surrendering or pessimistic. This kind of thinking is right opportunism, and those who hold this view are called Rightists. For example, in the first cooperation between the two countries, our party openly opposed the Kuomintang Rightists. Then came Chen Duxiu's right opportunism, which disintegrated the counter-revolutionary forces and ruined the revolution.
Left, as opposed to right, refers to revolution and ideological progress. For example, the Spartak Regiment, the leader of the German 1 1 Month Revolution, is the left wing of the German Social Democratic Party and the predecessor of the German * * * Production Party. Another example is that He Xiangning and Liao, who actively supported the establishment of a revolutionary United front in cooperation with other countries within the Kuomintang, were all left-wingers of the Kuomintang. On the cultural front, the "Left-wing Writers Union" actively participated in the revolution.
At the beginning of the 20th century, Lenin and Stalin began to refer to the radicals and conservatives within the proletariat with the concepts of left deviation and right deviation respectively. At that time, the revolutionary power of the proletariat was still relatively weak, and radicals often brought great losses to the budding proletarian revolution, so radicals were harmful and wrong to the revolution. In order to express derogatory meaning, put quotation marks on the left word, that is, "left" inclination. The right deviation at that time, that is, the conservatives, may have delayed the revolutionary process, but it did not bring obvious losses to the revolution, so the word right deviation does not contain derogatory meanings. By the end of the 1920s, with the strength of the proletarian revolution, both radicals and conservatives would bring losses to the revolution to varying degrees, so they used "left" opportunism and right opportunism to divide the political line errors within the proletariat. Similarly, due to habit, the quotation marks on the "left" word have not been removed so far, and the quotation marks on the right word have not been added.
"Left" means that thought transcends a certain stage of the objective process, leaves the practice of most people at that time, leaves the reality at that time, and falls into fantasy and blindness. It can be said that "Left" is the extreme of left metaphysics. In form, it is left, but in fact, it abandons the revolutionary reality of left and unilaterally strengthens revolutionary aggression. Politically, it is often manifested in expanding the scope of attack and carrying out impatient and aggressive struggles. This kind of thinking is "Left" opportunism, and those who hold this view are called "Left" opportunism. For example, in the history of China, Wang Ming's "Left" opportunism caused serious losses to the China revolution and the Party.
