政治的运行有着两种截然相反的逻辑：一种是现实主义逻辑，它驱使权力主体去做政治上正确的事；另一种是规范主义逻辑，它要求权力主体去做道德上正确的事。现代政治理论用正当性统一了上述两种逻辑，一个正当的政体必须既要做政治上正确的事，也要做道德上正确的事，而保护弱者就是最基础的道德上正确的事。在权力主体与权力客体间的复杂博弈中，保护弱者逐渐衍化为一种道德上不正确的“政治正确”，而随着各种反“政治正确”运动的兴起，现代政治的正当性受到了普遍质疑。要重建正当性，当代政治必须致力于消除社会范围内的权力不平等。

There are two different kinds of logics of political operationOne is called realism, which drives those in power to do the right things in the political senseThe other is called normativism, which requires those in power to do the right things in the moral senseModern political theory united these two with the concept of legitimacyNot only does a legitimate regime need to do the right things in the political sense, but it also needs to do things in a morally right wayProtecting underprivileged groups is the most basic case of things which are both politically right and morally rightHowever, it was gradually described as some kind of “political correctness” which is, in fact, morally incorrect during the complicated games between those in power and those without powerWith the rise of movements against “political correctness”, modern politics is in a serious legitimacy crisisTo rebuild its legitimacy, modern politics must be committed to eliminating inequality in power within the scope of the society
