This all started with s.o. being offended by it while watching the original interview, but how can you come to such a conclusion based on that? Did the female student's lecture attendance/signup rate plummet since that interview? Is there any kind of imperial evidence that this person's shirt is making female students turn away from science?
I honestly don't understand how it's even possible to get to that conclusion. If there's s.o. interested in a specific field and (s)he witnesses a major scientific breakthrough, then the last thing on your mind would be '...but how could the person be wearing that?'.
If you're offended by it, then ask why this happened in the first place, because maybe there's an actual good explanation behind it.
For me it's in the same category as people saying they don't want anything to do with computers because Turing was gay - how does one thing have anything to do with the other?
