Yes, killing Nazis is fun. But even as an antifascist, left leaning German, I'd like to remind people of the fact that fighting in WWII was mandatory for German men. Again, yes, the vast majority of German soldiers were indeed Nazis and they willingly fought for Hitler, they didn't need to be forced at all. Fuck these people.
However, there are other examples: My great grand dad was member of the SPD when the Nazis came to power, he was interned in Dachau for a short time in 1933, and forced to join the Wehrmacht. He fell somewhere in Russia in 1942.
Not defending Nazis here, just saying. A substantial number of Germans were forced to fight against their will, not wanting to fight was defeatism according to the Nazis, and defeatism was usually punished by execution.
Now have fun killing Nazis, by all means. Just be aware of this historical fact while doing so. Thank you.
