Zero argument on the larger point of Hitler’s idolization of America (the worst bits), quite familiar with it already. Hitler also admired Jim Crow laws and wrote about them specifically.
My point is that I’ve never encountered a reliable source to the specific claim that the Nazi salute took inspiration from the Bellamy salute, rather than being coincidentally similar. The wiki page linked even purports the origin of the Nazi salute to be the “Roman salute”, albeit itself based on bad history.
It’s a point I’d love to be able to make when having this same argument with folks, but I’m not going to tell people that the Nazi salute was based on the Bellamy salute without a better source than a Wikipedia article that claims otherwise.
That’s my understanding as well, with some “Roman” origin claimed, possibly as propaganda given how the Nazi party liked connecting themselves to ancient Rome as some kind of claim to legitimacy.
I’d love to be able to add the Bellamy salute inspiration bit in when I do have this conversation with folks, but I’d need a better source before I do.
