Help to understand this phrase? 作者首先提到了中国 媒体对于西方世界民主制度的一贯批判手法

The writer first mentions that the Chinese media have always been critical of one thing in the Western World’s democracies.

I don't get "一贯批判手法."  I suppose it means the last part of the English translation, but I don't get it.
Some issues with your translation:


一贯（的） means typical/consistent, not one thing. In this sentence, 一贯批判手法 could be translated as typical/consistent criticism
The original sentence focused on the criticism itself instead of the phenomenon of "the Chinese media being critical of democracies"


IMHO, a better translation would be,


  The writer first mentions typical criticism of the Chinese media on the Western World’s democracies.
