What is the difference between left leaning and right leaning ideas in history?

Left-leaning refers to the tendency to seek political progress and sympathize with working people. On the other hand, the "leftist" tendency in quotation marks refers to the tendency of political ideology to transcend objectivity, detach itself from the conditions of social reality, and fall into utopia, blind movement, and adventure. Therefore, in order to express the derogatory meaning, quotation marks are added to the left character, that is, "left" leaning, to distinguish it from the real left.

The "leftist" ideology is manifested in the eagerness for success, the subjective exaggeration of the revolutionary forces, the contempt for the enemy's strength and objective difficulties, and the adoption of blind and risky actions in the course of revolution and construction; or to confuse two kinds of contradictions of different nature within the revolutionary organization and adopt a policy of brutal struggle and ruthless attack; Or implement the doctrine of closing the door on the issue of the Confederates and bring down everything. If "leftist" ideology is formed into a systematic and complete line and implemented in practice, it becomes "left" opportunism or "left" adventurism. "Right-leaning" refers to the tendency of political and ideological understanding to lag behind reality, to be unable to change and advance with the changed objective situation, and even to go against the objective law of development.

If right-leaning ideology is formed into a systematic and complete line and is implemented in practice, it will become right-leaning opportunism. Right-leaning opportunism often abandons principles in political struggles and seeks compromise at the expense of the fundamental interests of the proletariat, which is also called right-leaning capitulationism. Right-leaning opportunism negates the basic tenets and principles of Marxism, overestimates the enemy's strength and underestimates the revolutionary forces in the revolutionary struggle, does not dare to actively mobilize and organize the masses to carry out struggles, misses favorable opportunities, and even retreats and flees in pessimism and disappointment.

In the later period of the Northern Expedition, the right-leaning ideology represented by Chen Duxiu developed into a capitulationist line.

To put it simply, left-leaning is too aggressive, subjective more than objective; Right-leaning is too backward, and the objective is greater than the subjective.

Left-leaning adventurism, right-leaning capitulationism.

It doesn't make a difference, it's just an excuse for the whole person...

Leftists are generally radical and advocate social change; Right-leaning is generally conservative and advocates bowing to those in power.

Right-leaning is conservative, lagging behind, delaying the opportunity, causing harm, and "not taking action when it is time to act." Left-leaning is ignorance of or transcendence of objective reality (law), excessive or advanced, and "must not be done (should)".

Right-leaning ideology refers to being conservative and calm.

Left-leaning ideology refers to radical and adventurous.

Left-leaning is radical, right-leaning is conservative, and neither is in line with reality.
