The left wing refers to the radical right wing, and the conservative left wing generally represents truly progressive ideas. The right wing generally represents the retrogression and conservative thinking of the old class and the division standard of the left and right factions in the West. The slogan of the French Revolution is very beautiful, called "Freedom, Equality and Fraternity". But any exciting slogan has one disadvantage, that is, it can't stand scrutiny. Everyone's talent and living environment are different. If everyone is allowed to develop freely, their wealth and status will not be equal. If everyone wants to be "equal" economically, it will inevitably limit the freedom of the strong to protect the weak. The left and right factions originated from the French Constitutional Convention, but were soon shaped into two factions that had nothing to do with the original intention. Among them, the left supports equality, emphasizes building a welfare state, and helps the weak more through state intervention. Rightists emphasize freedom, oppose excessive welfare, support competition, oppose state intervention, emphasize the establishment of a "weak" government, and oppose excessive restrictions on the strong. But the difference between left and right is only based on the emphasis on equality and freedom. The left is more equal and the right is more free. They all have the same understanding of the basic rights of equality and freedom. The so-called extreme left is to push leftist thinking to extremes and break through the "bottom line of freedom". In order to obtain indiscriminate justice and abolish most freedoms, we must build an incomparably powerful state machine and put all people's activities under the control of the state. The so-called extreme right, if we push the correct thinking to the extreme, break through the "bottom line of equality." The opposition that the state restricts the strong is interpreted as asking the strong to control the state to bully the weak, claiming that "the state exists for the strong" (Stolypin), practicing oligarchy, and canceling all protection and freedom for the weak.
