TESL equivalent for BM, thoughts?

(reddit MY is taken over by reactionaries so I run here)

So, BM. Lots of noise. People say because lack of love/lack of patriotism etc. But nobody considered that it might be poorly taught!

So, guys, especially if you are in linguistics and education, how do you see this? Is BM poorly taught in SJKs, and is a more systemic, holistic "game plan" needed? (pedagogy is the word I think?)

Maybe create a new discipline out of this?
