I think it was said in a slightly weird fashion, but i dont' think it was handled poorly at all. If anything I'm glad they mentioned the fact that it was there for anyone that doesn't want to see that.
People get murdered in a ton of anime, and they give that the same amount of attention. For some reason people are a little more "sensitive" about the subject of rape. Everyone has something they are sensitive about. If they were making rape jokes I can see it some people taking issue with it. Other then that its fine. Keep up the good work.
