I am part german...although I dont claim it as much as I tout my Irish and native american heritage, but I am really a heinz 57.
There has been some talk about possible jewish and african american ancentory as well. However, my dad is german about half german and although he is very religious, thus homophobic, he only racists against mexicans but where he lives, everyone hates the mexicans so I cant blame that on his german roots. Aside from those flaws, he is a very honest person...kinda has an aspie's honesty of telling it like it is. As far as mean, well he is not mean, unless you are an athiest (or he thought you were one), a percieved satan worshiper (aka goth), mexican or gasp! homosexual. But I still cant blame that on the fact his german, cause his dad is pure german and is the nicest man I know, although he is alittle shy. I think he is an aspie too. When I visit him, we watch the history channel together and discovery and Nat Geo. He is like me, I dont have much interest in watching fiction...unless it is really good, but love to watch educational channels.
I however dated a german who fit the decription your mother potrays, but people are individuals and should not all be judged by the actions of a small sample of folks.
