Overall your post doesn't really qualify for discussion, sadly. But to speak about this particular quote above, out of your message.
If you want to compare this particular salute with a Nazi salute, than this is perfectly fine by me; I had my own qualms. But, and this is a big but(!) it was not the German president who did that! And last but not least, the "German Government" was not present at the Olympic Openings in London.
Should do your research before saying such things. hint: Walther Tröger
I wasn't being too serious. It was mostly a joke.
