Prescriptive versus descriptive English

I read the Q&A for this lesson on collective nouns and the discussion at https://progress.lawlessfrench.com/is-this-english-correct and I see where Kwiziq is coming from. However, it would clearer for many Engliish speakers if you left out the "how it is in English" versus "how it is in French" comparisons. There are too many interpretations of collective nouns in different forms of English, and many of us haven't learnt the English prescriptions, so we are probably making frequent mistakes in English. In other words, just give teach the French grammar.
