Halte die Klappe und lehre Deutsch

"Stop the nonsense and learn German", I think the nonsense is coming from the Germans, who refuse to acknowledge a deadly problem to their people.

No, that would be “Shut up and teach German”...anyway, whining about matters never helps. While widely disregarded here among the moaners and nay-sayers, there are plenty of people in Germany fed up with Merkel’s madness and grass roots opposition is growing.

I was trying to say, “Shut up and teach German.”
