How do we discuss value judgments and factual judgments?

The BCI and Xinjiang cotton incidents brought to the table a heated debate between Shi Zhan and several scholars from the Fudan Institute of China.

Originally, I really agreed with the articles written by my teacher, and analyzed problems rationally and calmly.

As a result, the teachers from the Academia Sinica used impassioned words to describe the teachers as elites.

Teacher Shi Zhan calmly analyzed the whole process, and told the whole incident with rigorous logic. But it did not respond to the same attack from several teachers in the study.

Several teachers of the Academia Sinica used sharp words, and there were many provocative and derogatory words in them, but they did tell their own logic and analysis process.

How should it be understood.
