单词都懂，句子有歧义，请问哪个是正解？

The whole teeming multiplicity of the world’s cultures, developed (in the older sense of the word) through the labour and imagination of all of human history, is now to be placed under a single standard of value, and all which do not fit that standard are to be discarded with the most damning judgement the utilitarian can make useless:

The political public, unattached to any standards of judgement other than those provided by ethnicity, locality, party or passion … will be useless to the political culture of a modern society.

请问加粗部分是修饰most damning judgement吗？然后，意思是这种judgement的内容被实用主义认为是没用的吗？
