I'm in my mid 40s now, and I've been thinking about the differences these days, if there are any because maybe people feel there's not, in how people, especially girls, first understand the concepts of rape and abortion.
I don't know when I became aware of the concepts, maybe late in primary school? With abortion I got the impression it was about 'getting rid' of a 'baby' in some sense. I don't think I had any sense it was like literally a viable life or actually that it was bad per se, but certainly it was sort of sad but there were good reasons for it. I now feel abortion should be portrayed as a vital part of women's rights and healthcare, and I'm pleased that's how my teen seems to have understood it from the start.
Rape - I guess I thought it was sort of 'dirty' and I'd probably internalised some idea that it was about a man wanting a woman so much that he did that to her. Not that it was nothing to do with attraction and all about power, denying consent and boundaries and intense misogyny.
Don't know if these ramblings make sense to anyone, but as I said, I'm interesting in how the messages about what these things are have changed over the decades.
