I think it is great he reminds them every time they are not invited to the party inside. Very funny.

I also see the German left hasn't changed their arguments since... basically, the 1980s.

Their heads were about to explode when Ronald Reagan dared to visit a cemetary of German WW2 veterans around 1986 or so. He must have been a nazi too!

In Germany, you are not allowed to reach out and try to mend broken bonds. Not if the left can do anything about it.
