Well, it's a nice sentiment. But yet, I don't speak German.
Lucky you.
He never did explain what the hell that meant, but there was a time when we had a conservative wacko group running around trying to ban the teaching of German in schools supposedly as a moronic "patriotism" thing. They'd change the names of stuff like German Shepherds into "police dogs" lest the snowflakery be offended by hearing the word "German". There were even Dachshunds ripped from their owners and stoned to death in the street for the crime that we gave them a German name. It's where mob mentality and its attendant ignorance lead.
I dunno, actively rejecting a language and trying to make sure nobody else speaks it, that's just pig-ignorance.
