You can't be a proud american AND a Nazi at the same time. It can't be done.
There was even a war about it, the whole world was involved if you recall... and the whole world told the nazis to go get fucked.
So you're either one or the other, and if you choose Nazi, get out of America. Though... I'm not too sure where you will go because, again, the whole world told your kind to go get fucked.
