Given that racists and slavers used the “natural physical strength” of black people to justify putting them on hard labor and some medics still think that blacks has higher resistance to pain, I wonder if when black athletes started to join mixed race sport teams, some racist would have used the same “biological advantage” argument that now transphobes use against trans athletes to claim it was “unfair” for black to compete against whites to justify segregation.
A had experience, A told B, B told me. If the story is a lie, A is the one who lied. But I will never know, because I do not talk with B anymore (lives in another country) and I have never met A.
Another possibility is that it happened, just not the way I was told. Perhaps only one person stood and did the salute, perhaps the salute did not happen but the teacher instead though Adolf Hitler was head or state (or someone from his faction). Or I just remember it wrong, it was not A who had the experience and it is just an urban legend. It was 10+ years ago, after all.
Either way, I hope that story is not real.
It’s a funny story, I just don’t know why you give it any credibility given how many highly improbable things have to be true. It’s far more likely that it was a story told solely for humourous reasons, or it was a minor fib that became more humourous over time.
