Speaking Japanese does not mean higher class. or higher moral standards.
I only said that she speaks good Japanese and posted an example of it only to show why Japan had the expression of "Goddess of Democracy" for her. It would be a little strange for Japanese to attach such an name on her if she couldn't even explain herself to a Japanese audience. So it's not some shallow monkey-see other western stuff so monkey-do it with making term "Goddess of democracy". There are many more examples of her engaging with a Japanese audiance. I think she's far more engaged with the Japanese audience than English speakers. Which probably makes sense to do since Joshua Wong already can make the protester case to English speaking audience. So Agnes Chow expands their call by being able to make the case to a Japanese audience.
But actually, I think she is quite incrediable if I have to be honest.
