An interview with the head of the Munich English Language Teachers Association that makes a lot of sense. The native/non-native teacher argument is unnecessary.What matters is being a good enabler of English language acquisition.
The next step may be to communicate this with students who often state a request for British English in my lessons and compare it to Hochdeutsch. The idea that it is the standard or ´correct`version of English.
