I agree. It seems to me to be an extension of the trope of cartoon villains having certain physical features - often painted as a clear outward sign of their villainy - meaning that people who are perfectly nice folk, but who happen to have physical characteristics that are not traditionally envied... well, it's obviously because they're inherently bad, isn't it? If they were nice, kind people, they would never look like that. It's their inner ugliness that's manifesting externally.
I can't for the life of me think what the people studying and chattering about this hope to achieve - apart from maybe to demonise many men who have the same physical condition but happen not to be evil genocidal monsters.
I lived in Austria for a while and, considering that Hitler was Austrian, well... hmm... you know... all of the people that I knew and met... were not one iota like Hitler whatsoever. Shockingly, the vast majority of them were very nice, pleasant people - and even the few that I didn't get on with were maybe only a bit grumpy or had a different personality from me; not a single one of them was a mass-murderer.
Of all the useful, positive things that these scientists could be spending their time doing...
