Just use a different image. It's a pretty simple ask. For fuck's sake, this shouldn't be so hard to understand with a tiny shred of human empathy.
This is ignoring that the photo itself is completely innocuous. People who complain about the Lena photo, I suspect that 99.9% of them have absolutely no problem with AOC's appearance at the Met Gala in her Eat Mor Chikin dress. Which, from a perspective of propriety, there is no possible differentiation from the Lena photo. Their complaint has to do with the photo's origins, not with the photo itself. And, sorry, but the world isn't ruled by the pearl clutchers on their fainting couches.

It's like asking Americans to use metric.
