I recall my Dad telling me about the German American Bund meetings in the Northwest being countered by pro American and anti Hitler meetings put on by other German Americans. In short, not even a majority of German Americans were pro Hitler although many were.
I would contrast that with the Muslims in America where only a handful of brave Muslims speak out against the Islamists.
That was something that did occur and I know Germans who rescinded their citizenship when they learned what the Nazis had done.
Where are the Muslim anti-terrorist rallies, where are the muslims with Peace signs standing on the sides of the roads when the Islamists march down the streets in Birmingham or London screaming about killing the infidel?
Where are these handful of brave Muslims you speak of?
