I'm Polish and believe me when I say that I would also prefer Germany to learn different lessons from those your government claims to follow. The very idea that what nazis did wrong was targeting Jews instead of creating authoritarian stratified far right society that eventualy decided to displace and genocide people based on somewhat loosely described traits is not only a gross and dumb oversimplification, it's gross and end evil to even propose. Fascism fits the class interests of the rich and powerfull of today just as much, if not more, as it did a century ago. Germany government siding with Israel in favour of the genocide they're commiting is not just for show, they're very happy that defending genocide became a position close to political center. In my opinion, that is.
