Perhaps the antidote is a long holiday in Bavaria, where they will see both the best and the worst of corresponding attitudes to their own through the Cherman lens. This may at last give them some perspective - perhaps even the ability to shift from their long-held and hoary old thoughts to some with less lichen and moss growing on them?
Well, I have worked in Bavaria and my best German friends are in Bavaria, I talk to them regularly and have holidayed there with them on many occasions. My daughter did a school exchange with a school at Holfeldt and via that we stayed on her exchange students farm in Wonsees for a week and got pissed with them ever night. My friend Brian was i/c the engines on the Typhoon and another was Chief Electrical Engineer on the Tornado, we stayed with both of them in Munich many times. Apart from that our main competitors all over the world were German Companies in two businesses I worked for for a total of 12 years.
So dont try to tell me anything about Bavaria or Germany. I know all about the Ossies and Prussies too,...
Make no mistake the Germans are the biggest funders of the EU and believe they are in charge, France holds the position of Barney Rubble "yes Fred!".
I haf a great great grandad that was Cherman. Can I claim citizenship there? I have a fancy to be a member of the new master race you seem to feel is imminent.
On the other hand, I am probably far too diluted now with melting pot stuff.
Now, after your stints in Chermanland, did you find a-one of your hoary old ideas rather too brittle and so swap it for another? For example, did Oktoberfest move you from a taste for flat warm beer (known to all as "wet dog") to the delights of a fine lager?
I myself have a preference for the engineered products of that fine nation, for use in my woodworking. They seem to work properly, unlike many a British item I have felt disappointment in. I will be annoyed if I find myself in need of a spindle moulder that costs far more post-Breixit than when we were all good friends! I will blame you, amongst others.
