No, I am not gong to be quiet, and you are definitely none of those "rational" people.
Yes, my argument is clear and concise while yours is not at all.
And you must be one of the paid lackeys posting in favour of that crap York pretend "school"?
No reason to waste any time on your "arguments" in detail; to say that garbage York pretend "school" is one of the thousands of crappy training centres in China is just enough. Nothing else needs to be addred.
Crappy training centres in China have no credibility at all, they are language mills that are not to be taken seriously for the lack of quality education they provide.

you should stay quiet and let the rational people speak
