The second paragraph to the right of the photo talks about how our perception of these things changes with time, and while it seems shocking to us now it would once have been taken for granted. It was a big news story at the time and was not taken for granted.

Edit: I guess my wording was a bit off. I meant to say that it was not within the cultural norms of the time. As worded, it sounds like I’m discussing its frequency rather than its level of acceptance - that’s my bad.
