Not much to say about the article; the comments, though, are another story. Don’t really want to organize my points well, and definitely not interested in online word battles, so I’m just posting them here.

Quintin Lam 數學攞Lv.2入到香港大學更能反映香港重文輕理的白痴教育制度。

利申中文2咗所以乜春都入唔到

Belinda Chan 無語文表達就算數學家發表咩偉論都要人地明

So many things wrong in just one sentence.

  1. A lot of mathematics is communicated via standard (or de facto standard) notations; even when the grammar is not correct the idea is often understandable. In contrast, get some language professors to read some mathematics research papers. I bet you a nickel they don’t get shit.
  2. A society consists of many people, each with different roles. Suppose a mathematician wants to spread some idea, but he has terrible language skills. He can simply find another person who can understand him and is better at languages to help him.
  3. HKDSE Chinese exams consist of not only the use of the language, but also the analysis and appreciation of literature, and the composition of fictional stories. Contrast with HKALE Use of English. (I have not actually looked at Use of English past papers or syllabuses; this statement is made on the assumption that the subject was called “Use of English” and not “English” for a logical reason.)

Ken Chan 因為以工程師為例你整完一件product都要寫份靚靚仔仔嘅report 出嚟比你老闆睇，語文唔掂嘅話分分鐘份report會煩過你整個product

There are many types of engineers, not all of them have to submit very well-written (in terms of language use) reports to their bosses. For some jobs it may be more important to be able to draw accurate diagrams, as long as the language is understandable. Cf. point 2 above – a company consists of many people.

熊明德 - 阿臣 Bearsniffsonsociety 中、英文係溝通用、表達思考嘅工具， 考試成績太弱係好難說服人哋你有「基本語文能力」。

Except the use of languages (esp. Chinese) is not the main point of the HKDSE exams – see point 3 above.
