No, France was invaded by Germany along with Poland, Greece, Jugoslavia, Netherlands and Belgium, the aggression was initiated by Germany. Seems you should get your facts right.
I´m not here to give you history lessons but here we go.
Danzig was no longer German territory after the end of WW1. As a German you would have had to go to Germany or you are a citizen of Poland. It's actually quite simple. Those were the conditions for ending the war. I hope you know that in such cases you have to give things up whether you want to or not.
And with what the Nazis did in Poland and across half Europe in WW2, it's no wonder that there are retaliatory measures. And I'm not glorifying either as good.
If you like Nazis and Hitler so much, you should at least update your information about them.
But saying some nonsense to justify it is laughable.
