Confrontational criticism and even criticism for the sake of criticism have become popular on the Internet. Radical liberals constitute the main driving force of such criticism. They take such criticisms that are without boundaries as freedom of speech.

Criticism in Chinese society has been expanded thanks to the reform and opening up process, Internet technology and globalization.

But it must stick to the basic principle that it should help improve the country's political system rather than agitate it.

All countries' political systems are blended into the constitution. It is a misunderstanding of law if one believes criticism only has to abide by law without adhering to the political bottom line.

Liberal intellectuals endorse a free mind and some turn a deaf ear to any reminder of the bottom line. They ignore the differences of political systems between China and the West and view Western standards as universal.

Radical liberals are cherishing an illusion that there will be a subversive change in Chinese society, or even a collapse of the current social system. They probably believe that going against the ruling Party is a promising undertaking and the universal values promoted by the West will prevail eventually.

How the Chinese national system and mainstream society co-exist with these radical liberals is a pending issue China has to deal with.

Objectively speaking, these radical liberals have made contributions to society, speeding up China's reform.

The problem is that these people must know where society's bottom line is. They need to restore respect to the rule of law.

No matter what their political beliefs are, they cannot cross the red line of laws.

In the pursuit of so-called free speech, these people must know that provoking China's basic system is doomed to fail. The constitution has determined China's national system, and whether they like it or not, these Western political values cannot be promoted as freely as they want.

The group of radical liberals is a minority force in China, whose true pursuit is not shared by China's masses.

Though they embrace populism tactically, their lifestyle and source of resources actually go against the advocacy of populism.

This group, under the deep influence of Western ideology, has underestimated the stability of China's grand political system. The country's current political institution is shaped by history, which cannot be changed by a few radical liberals. They should not attempt to dominate the country's direction.
