Just something I’ve had on my mind for a while.
I've done quite a bit of research on the 1936 Olympics and have never come across this. Which leaves me to assume that, rather than a rebutting excuse, Hitler simply chose to ignore it and focus on German medalists.
His closest comment on the matter that from another redditor, but as you'll see it's just him trying to mock the US for letting African Americans take part in the Olympics for them.
Specifically, look at the comments made by u/georgy_k_zhukov and edit: and u/prufrock451
